/**
View class responsible for rendering the `<tbody>` section of a table. Used as
the default `bodyView` for `Y.DataTable.Base` and `Y.DataTable` classes.
Translates the provided `modelList` into a rendered `<tbody>` based on the data
in the constituent Models, altered or ammended by any special column
configurations.
The `columns` configuration, passed to the constructor, determines which
columns will be rendered.
The rendering process involves constructing an HTML template for a complete row
of data, built by concatenating a customized copy of the instance's
`CELL_TEMPLATE` into the `ROW_TEMPLATE` once for each column. This template is
then populated with values from each Model in the `modelList`, aggregating a
complete HTML string of all row and column data. A `<tbody>` Node is then created from the markup and any column `nodeFormatter`s are applied.
Supported properties of the column objects include:
* `key` - Used to link a column to an attribute in a Model.
* `name` - Used for columns that don't relate to an attribute in the Model
(`formatter` or `nodeFormatter` only) if the implementer wants a
predictable name to refer to in their CSS.
* `cellTemplate` - Overrides the instance's `CELL_TEMPLATE` for cells in this
column only.
* `formatter` - Used to customize or override the content value from the
Model. These do not have access to the cell or row Nodes and should
return string (HTML) content.
* `nodeFormatter` - Used to provide content for a cell as well as perform any
custom modifications on the cell or row Node that could not be performed by
`formatter`s. Should be used sparingly for better performance.
* `emptyCellValue` - String (HTML) value to use if the Model data for a
column, or the content generated by a `formatter`, is the empty string,
`null`, or `undefined`.
* `allowHTML` - Set to `true` if a column value, `formatter`, or
`emptyCellValue` can contain HTML. This defaults to `false` to protect
against XSS.
* `className` - Space delimited CSS classes to add to all `<td>`s in a column.
Column `formatter`s are passed an object (`o`) with the following properties:
* `value` - The current value of the column's associated attribute, if any.
* `data` - An object map of Model keys to their current values.
* `record` - The Model instance.
* `column` - The column configuration object for the current column.
* `className` - Initially empty string to allow `formatter`s to add CSS
classes to the cell's `<td>`.
* `rowIndex` - The zero-based row number.
* `rowClass` - Initially empty string to allow `formatter`s to add CSS
classes to the cell's containing row `<tr>`.
They may return a value or update `o.value` to assign specific HTML content. A
returned value has higher precedence.
Column `nodeFormatter`s are passed an object (`o`) with the following
properties:
* `value` - The current value of the column's associated attribute, if any.
* `td` - The `<td>` Node instance.
* `cell` - The `<div>` liner Node instance if present, otherwise, the `<td>`.
When adding content to the cell, prefer appending into this property.
* `data` - An object map of Model keys to their current values.
* `record` - The Model instance.
* `column` - The column configuration object for the current column.
* `rowIndex` - The zero-based row number.
They are expected to inject content into the cell's Node directly, including
any "empty" cell content. Each `nodeFormatter` will have access through the
Node API to all cells and rows in the `<tbody>`, but not to the `<table>`, as
it will not be attached yet.
If a `nodeFormatter` returns `false`, the `o.td` and `o.cell` Nodes will be
`destroy()`ed to remove them from the Node cache and free up memory. The DOM
elements will remain as will any content added to them. _It is highly
advisable to always return `false` from your `nodeFormatter`s_.

Creates the table's `<tbody>` content by assembling markup generated by
populating the `ROW\_TEMPLATE`, and `CELL\_TEMPLATE` templates with content
from the `columns` and `modelList` attributes.
The rendering process happens in three stages:
1. A row template is assembled from the `columns` attribute (see
`_createRowTemplate`)
2. An HTML string is built up by concatening the application of the data in
each Model in the `modelList` to the row template. For cells with
`formatter`s, the function is called to generate cell content. Cells
with `nodeFormatter`s are ignored. For all other cells, the data value
from the Model attribute for the given column key is used. The
accumulated row markup is then inserted into the container.
3. If any column is configured with a `nodeFormatter`, the `modelList` is
iterated again to apply the `nodeFormatter`s.
Supported properties of the column objects include:
* `key` - Used to link a column to an attribute in a Model.
* `name` - Used for columns that don't relate to an attribute in the Model
(`formatter` or `nodeFormatter` only) if the implementer wants a
predictable name to refer to in their CSS.
* `cellTemplate` - Overrides the instance's `CELL_TEMPLATE` for cells in
this column only.
* `formatter` - Used to customize or override the content value from the

return string (HTML) content.
* `nodeFormatter` - Used to provide content for a cell as well as perform
any custom modifications on the cell or row Node that could not be

performance.
* `emptyCellValue` - String (HTML) value to use if the Model data for a
column, or the content generated by a `formatter`, is the empty string,
`null`, or `undefined`.
* `allowHTML` - Set to `true` if a column value, `formatter`, or
`emptyCellValue` can contain HTML. This defaults to `false` to protect
against XSS.
* `className` - Space delimited CSS classes to add to all `<td>`s in a
column.
Column `formatter`s are passed an object (`o`) with the following
properties:

* `rowIndex` - The zero-based row number.
* `rowClass` - Initially empty string to allow `formatter`s to add CSS

They may return a value or update `o.value` to assign specific HTML
content. A returned value has higher precedence.

They are expected to inject content into the cell's Node directly, including
any "empty" cell content. Each `nodeFormatter` will have access through the
Node API to all cells and rows in the `<tbody>`, but not to the `<table>`,
as it will not be attached yet.
If a `nodeFormatter` returns `false`, the `o.td` and `o.cell` Nodes will be
`destroy()`ed to remove them from the Node cache and free up memory. The
DOM elements will remain as will any content added to them. _It is highly
advisable to always return `false` from your `nodeFormatter`s_.

* current state tree and the given `action`. Its return value will
* be considered the **next** state of the tree, and the change listeners
* will be notified.
*
* The base implementation only supports plain object actions. If you want to
* dispatch a Promise, an Observable, a thunk, or something else, you need to
* wrap your store creating function into the corresponding middleware. For
* example, see the documentation for the `redux-thunk` package. Even the
* middleware will eventually dispatch plain object actions using this method.
*
* @param {Object} action A plain object representing “what changed”. It is
* a good idea to keep actions serializable so you can record and replay user
* sessions, or use the time travelling `redux-devtools`. An action must have
* a `type` property which may not be `undefined`. It is a good idea to use
* string constants for action types.
*
* @returns {Object} For convenience, the same action object you dispatched.
*
* Note that, if you use a custom middleware, it may wrap `dispatch()` to
* return something else (for example, a Promise you can await).

<h1>Welcome to STORYBOOK</h1>
<p>
This is a UI component dev environment for your app.
</p>
<p>
We've added some basic stories inside the <code style={styles.code}>src/stories</code> directory.
<br />
A story is a single state of one or more UI components. You can have as many stories as you want.
<br />
(Basically a story is like a visual test case.)
</p>
<p>
See these sample <a style={styles.link} href='#' onClick={this.showApp.bind(this)}>stories</a> for a component called <code style={styles.code}>Button</code>.
</p>
<p>
Just like that, you can add your own components as stories.
<br />
You can also edit those components and see changes right away.
<br />
(Try editing the <code style={styles.code}>Button</code> component
located at <code style={styles.code}>src/stories/Button.js</code>.)
</p>
<p>
This is just one thing you can do with Storybook.
<br />
Have a look at the <a style={styles.link} href='https://github.com/kadirahq/react-storybook' target='_blank'>React Storybook</a> repo for more information.
</p>
<p style={styles.note}>
<b>NOTE:</b>
<br />
Have a look at the <code style={styles.code}>.storybook/webpack.config.js</code> to add webpack
loaders and plugins you are using in this project.
</p>
</div>

The YUI global namespace object. This is the constructor for all YUI instances.
This is a self-instantiable factory function, meaning you don't need to precede
it with the `new` operator. You can invoke it directly like this:
YUI().use('*', function (Y) {
// Y is a new YUI instance.
});
But it also works like this:
var Y = YUI();
The `YUI` constructor accepts an optional config object, like this:
YUI({
debug: true,
combine: false
}).use('node', function (Y) {
// Y.Node is ready to use.
});
See the API docs for the <a href="config.html">Config</a> class for the complete
list of supported configuration properties accepted by the YUI constuctor.
If a global `YUI` object is already defined, the existing YUI object will not be
overwritten, to ensure that defined namespaces are preserved.
Each YUI instance has full custom event support, but only if the event system is

Registers a YUI module and makes it available for use in a `YUI().use()` call or

tool.
Shifter will automatically wrap your module code in a `YUI.add()` call along
with any configuration info required for the module.
@example
YUI.add('davglass', function (Y) {

Y.log('Dav was here!');

executed whenever the module is attached to a specific YUI instance.
@param {YUI} fn.Y The YUI instance to which this module is attached.
@param {String} fn.name Name of the module
@param {String} version Module version number. This is currently used only for
informational purposes, and is not used internally by YUI.
@param {Object} [config] Module config.
@param {Array} [config.requires] Array of other module names that must be
attached before this module can be attached.
@param {Array} [config.optional] Array of optional module names that should
be attached before this module is attached if they've already been
loaded. If the `loadOptional` YUI option is `true`, optional modules
that have not yet been loaded will be loaded just as if they were hard
requirements.
@param {Array} [config.use] Array of module names that are included within
or otherwise provided by this module, and which should be attached
automatically when this module is attached. This makes it possible to
create "virtual rollup" modules that simply attach a collection of other
modules or submodules.

/**
Utility method for safely creating namespaces if they don't already exist.
May be called statically on the YUI global object or as a method on a YUI
instance.
When called statically, a namespace will be created on the YUI global
object:
// Create `YUI.your.namespace.here` as nested objects, preserving any
// objects that already exist instead of overwriting them.
YUI.namespace('your.namespace.here');
When called as a method on a YUI instance, a namespace will be created on
that instance:
// Creates `Y.property.package`.
Y.namespace('property.package');
Dots in the input string cause `namespace` to create nested objects for each
token. If any part of the requested namespace already exists, the current
object will be left in place and will not be overwritten. This allows
multiple calls to `namespace` to preserve existing namespaced properties.
If the first token in the namespace string is "YAHOO", that token is
discarded. This is legacy behavior for backwards compatibility with YUI 2.
Be careful with namespace tokens. Reserved words may work in some browsers
and not others. For instance, the following will fail in some browsers
because the supported version of JavaScript reserves the word "long":
Y.namespace('really.long.nested.namespace');
Note: If you pass multiple arguments to create multiple namespaces, only the
last one created is returned from this function.
@method namespace
@param {String} namespace* One or more namespaces to create.
@return {Object} Reference to the last namespace object created.

This isn't guaranteed to be 100% accurate and won't work for anything other than
functions, but it can be useful for determining whether a function like
`Array.prototype.forEach` is native or a JS shim provided by another library.
There's a great article by @kangax discussing certain flaws with this technique:
<http://perfectionkills.com/detecting-built-in-host-methods/>
While his points are valid, it's still possible to benefit from this function
as long as it's used carefully and sparingly, and in such a way that false
negatives have minimal consequences. It's used internally to avoid using
potentially broken non-native ES5 shims that have been added to the page by
other libraries.

Performs a simple comparison between two version numbers, accounting for
standard versioning logic such as the fact that "535.8" is a lower version than
"535.24", even though a simple numerical comparison would indicate that it's
greater. Also accounts for cases such as "1.1" vs. "1.1.0", which are
considered equivalent.
Returns -1 if version _a_ is lower than version _b_, 0 if they're equivalent,
1 if _a_ is higher than _b_.
Versions may be numbers or strings containing numbers and dots. For example,
both `535` and `"535.8.10"` are acceptable. A version string containing
non-numeric characters, like `"535.8.beta"`, may produce unexpected results.

Callback functions specified via the options object or the `options`

transaction object as a parameter. See `Y.Get.Transaction` for details on
the properties and methods available on transactions.
@static
@since 3.5.0
@property {Object} options
@property {Boolean} [options.async=false] Whether or not to load scripts
asynchronously, meaning they're requested in parallel and execution
order is not guaranteed. Has no effect on CSS, since CSS is always
loaded asynchronously.
@property {Object} [options.attributes] HTML attribute name/value pairs that
should be added to inserted nodes. By default, the `charset` attribute
will be set to "utf-8" and nodes will be given an auto-generated `id`
attribute, but you can override these with your own values if desired.
@property {Boolean} [options.autopurge] Whether or not to automatically
purge inserted nodes after the purge threshold is reached. This is
`true` by default for JavaScript, but `false` for CSS since purging a
CSS node will also remove any styling applied by the referenced file.
@property {Object} [options.context] `this` object to use when calling
callback functions. Defaults to the transaction object.
@property {Mixed} [options.data] Arbitrary data object to pass to "on*"
callbacks.
@property {Document} [options.doc] Document into which nodes should be
inserted. By default, the current document is used.
@property {HTMLElement|String} [options.insertBefore] HTML element or id
string of an element before which all generated nodes should be
inserted. If not specified, Get will automatically determine the best
place to insert nodes for maximum compatibility.
@property {Function} [options.onEnd] Callback to execute after a transaction
is complete, regardless of whether it succeeded or failed.
@property {Function} [options.onFailure] Callback to execute after a
transaction fails, times out, or is aborted.
@property {Function} [options.onProgress] Callback to execute after each
individual request in a transaction either succeeds or fails.
@property {Function} [options.onSuccess] Callback to execute after a
transaction completes successfully with no errors. Note that in browsers
that don't support the `error` event on CSS `<link>` nodes, a failed CSS
request may still be reported as a success because in these browsers
it can be difficult or impossible to distinguish between success and
failure for CSS resources.
@property {Function} [options.onTimeout] Callback to execute after a
transaction times out.
@property {Number} [options.pollInterval=50] Polling interval (in
milliseconds) for detecting CSS load completion in browsers that don't
support the `load` event on `<link>` nodes. This isn't used for
JavaScript.
@property {Number} [options.purgethreshold=20] Number of nodes to insert
before triggering an automatic purge when `autopurge` is `true`.
@property {Number} [options.timeout] Number of milliseconds to wait before
aborting a transaction. When a timeout occurs, the `onTimeout` callback
is called, followed by `onFailure` and finally `onEnd`. By default,
there is no timeout.
@property {String} [options.type] Resource type ("css" or "js"). This option
is set automatically by the `css()` and `js()` functions and will be
ignored there, but may be useful when using the `load()` function. If
not specified, the type will be inferred from the URL, defaulting to
"js" if the URL doesn't contain a recognizable file extension.

Augments the _receiver_ with prototype properties from the _supplier_. The
receiver may be a constructor function or an object. The supplier must be a
constructor function.
If the _receiver_ is an object, then the _supplier_ constructor will be called
immediately after _receiver_ is augmented, with _receiver_ as the `this` object.
If the _receiver_ is a constructor function, then all prototype methods of
_supplier_ that are copied to _receiver_ will be sequestered, and the
_supplier_ constructor will not be called immediately. The first time any
sequestered method is called on the _receiver_'s prototype, all sequestered
methods will be immediately copied to the _receiver_'s prototype, the
_supplier_'s constructor will be executed, and finally the newly unsequestered
method that was called will be executed.
This sequestering logic sounds like a bunch of complicated voodoo, but it makes
it cheap to perform frequent augmentation by ensuring that suppliers'
constructors are only called if a supplied method is actually used. If none of
the supplied methods is ever used, then there's no need to take the performance
hit of calling the _supplier_'s constructor.

* Setting this property to true will populate the deprecated `subscribers` and `afters`

* If you are using these deprecated properties for a use case which the public API

`fire`d from any object in the YUI instance sandbox</li>
<li>Subscribe to DOM events</li>
<li>Subscribe to the execution of a method on any object, effectively
treating that method as an event</li>

and callback as the second. The `this` object in the callback will be `Y` unless
an override is passed as the third argument.
Y.on('io:complete', function () {
Y.MyApp.updateStatus('Transaction complete');

To subscribe to DOM events, pass the name of a DOM event as the first argument
and a CSS selector string as the third argument after the callback function.
Alternately, the third argument can be a `Node`, `NodeList`, `HTMLElement`,
array, or simply omitted (the default is the `window` object).
Y.on('click', function (e) {
e.preventDefault();
// proceed with ajax form submission
var url = this.get('action');
...
}, '#my-form');
The `this` object in DOM event callbacks will be the `Node` targeted by the CSS
selector or other identifier.
`on()` subscribers for DOM events or custom events `publish`ed with a
`defaultFn` can prevent the default behavior with `e.preventDefault()` from the
event object passed as the first parameter to the subscription callback.

Subscribe a callback function for each `Node` in the collection to execute
in response to a DOM event.
NOTE: Generally, the `on()` method should be avoided on `NodeLists`, in
favor of using event delegation from a parent Node. See the Event user
guide for details.
Most DOM events are associated with a preventable default behavior, such as
link clicks navigating to a new page. Callbacks are passed a
`DOMEventFacade` object as their first argument (usually called `e`) that
can be used to prevent this default behavior with `e.preventDefault()`. See

By default, the `this` object will be the `NodeList` that the subscription
came from, <em>not the `Node` that received the event</em>. Use
`e.currentTarget` to refer to the `Node`.
Returning `false` from a callback is supported as an alternative to calling
`e.preventDefault(); e.stopPropagation();`. However, it is recommended to
use the event methods.
@example
Y.all(".sku").on("keydown", function (e) {
if (e.keyCode === 13) {
e.preventDefault();
// Use e.currentTarget to refer to the individual Node
var item = Y.MyApp.searchInventory( e.currentTarget.get('value') );

/**
Method for initiating an ajax call. The first argument is the url end
point for the call. The second argument is an object to configure the
transaction and attach event subscriptions. The configuration object
supports the following properties:
<dl>
<dt>method</dt>
<dd>HTTP method verb (e.g., GET or POST). If this property is not
not defined, the default value will be GET.</dd>
<dt>data</dt>
<dd>This is the name-value string that will be sent as the
transaction data. If the request is HTTP GET, the data become
part of querystring. If HTTP POST, the data are sent in the
message body.</dd>
<dt>xdr</dt>
<dd>Defines the transport to be used for cross-domain requests.
By setting this property, the transaction will use the specified
transport instead of XMLHttpRequest. The properties of the
transport object are:
<dl>
<dt>use</dt>
<dd>The transport to be used: 'flash' or 'native'</dd>
<dt>dataType</dt>
<dd>Set the value to 'XML' if that is the expected response
content type.</dd>
</dl></dd>
<dt>form</dt>
<dd>Form serialization configuration object. Its properties are:
<dl>
<dt>id</dt>
<dd>Node object or id of HTML form</dd>
<dt>useDisabled</dt>
<dd>`true` to also serialize disabled form field values
(defaults to `false`)</dd>
</dl></dd>
<dt>on</dt>
<dd>Assigns transaction event subscriptions. Available events are:
<dl>
<dt>start</dt>
<dd>Fires when a request is sent to a resource.</dd>
<dt>complete</dt>
<dd>Fires when the transaction is complete.</dd>
<dt>success</dt>
<dd>Fires when the HTTP response status is within the 2xx
range.</dd>
<dt>failure</dt>
<dd>Fires when the HTTP response status is outside the 2xx
range, if an exception occurs, if the transation is aborted,
or if the transaction exceeds a configured `timeout`.</dd>
<dt>end</dt>
<dd>Fires at the conclusion of the transaction
lifecycle, after `success` or `failure`.</dd>
</dl>
<p>Callback functions for `start` and `end` receive the id of the
transaction as a first argument. For `complete`, `success`, and
`failure`, callbacks receive the id and the response object
(usually the XMLHttpRequest instance). If the `arguments`
property was included in the configuration object passed to
`Y.io()`, the configured data will be passed to all callbacks as
the last argument.</p>
</dd>
<dt>sync</dt>
<dd>Pass `true` to make a same-domain transaction synchronous.
<strong>CAVEAT</strong>: This will negatively impact the user
experience. Have a <em>very</em> good reason if you intend to use
this.</dd>
<dt>context</dt>
<dd>The "`this'" object for all configured event handlers. If a
specific context is needed for individual callbacks, bind the
callback to a context using `Y.bind()`.</dd>
<dt>headers</dt>
<dd>Object map of transaction headers to send to the server. The
object keys are the header names and the values are the header
values.</dd>
<dt>timeout</dt>
<dd>Millisecond threshold for the transaction before being
automatically aborted.</dd>
<dt>arguments</dt>
<dd>User-defined data passed to all registered event handlers.
This value is available as the second argument in the "start" and
"end" event handlers. It is the third argument in the "complete",
"success", and "failure" event handlers. <strong>Be sure to quote
this property name in the transaction configuration as
"arguments" is a reserved word in JavaScript</strong> (e.g.
`Y.io({ ..., "arguments": stuff })`).</dd>

/**
* @workInProgress
* @ngdoc directive
* @name angular.directive.ng:autobind
* @element script
*
* @TODO ng:autobind is not a directive!! it should be documented as bootstrap parameter in a
* separate bootstrap section.
* @TODO rename to ng:autobind to ng:autoboot
*
* @description
* This section explains how to bootstrap your application with angular, using either the angular
* javascript file, or manually.
*
* # Auto-bootstrap with `ng:autobind`
* The simplest way to get an <angular/> application up and running is by inserting a script tag in
* your HTML file that bootstraps the `http://code.angularjs.org/angular-x.x.x.min.js` code and uses
* the special `ng:autobind` attribute, like in this snippet of HTML:
*
* <pre>
<!doctype html>
<html xmlns:ng="http://angularjs.org">
<head>
<script type="text/javascript" src="http://code.angularjs.org/angular-0.9.3.min.js"
ng:autobind></script>
</head>
<body>
Hello {{'world'}}!
</body>
</html>
* </pre>
*
* The `ng:autobind` attribute without any value tells angular to compile and manage the whole HTML
* document. The compilation occurs as soon as the document is ready for DOM manipulation. Note that
* you don't need to explicitly add an `onLoad` event handler; auto bind mode takes care of all the
* work for you.
*
* In order to compile only a part of the document, specify the id of the element that should be
* compiled as the value of the `ng:autobind` attribute, e.g. `ng:autobind="angularContent"`.
*
*
* ## Auto-bootstrap with `#autobind`
* In rare cases when you can't define the `ng` namespace before the script tag (e.g. in some CMS
* systems, etc), it is possible to auto-bootstrap angular by appending `#autobind` to the script
* src URL, like in this snippet:
*
* <pre>
<!doctype html>
<html>
<head>
<script type="text/javascript"
src="http://code.angularjs.org/angular-0.9.3.min.js#autobind"></script>
</head>
<body>
<div xmlns:ng="http://angularjs.org">
Hello {{'world'}}!
</div>
</body>
</html>
* </pre>
*
* In this case it's the `#autobind` URL fragment that tells angular to auto-bootstrap.
*
* Similarly to `ng:autobind`, you can specify an element id that should be exclusively targeted for
* compilation as the value of the `#autobind`, e.g. `#autobind=angularContent`.
*
* ## Filename Restrictions for Auto-bootstrap
* In order for us to find the auto-bootstrap script attribute or URL fragment, the value of the
* `script` `src` attribute that loads angular script must match one of these naming
* conventions:
*
* - `angular.js`
* - `angular-min.js`
* - `angular-x.x.x.js`
* - `angular-x.x.x.min.js`
* - `angular-x.x.x-xxxxxxxx.js` (dev snapshot)
* - `angular-x.x.x-xxxxxxxx.min.js` (dev snapshot)
* - `angular-bootstrap.js` (used for development of angular)
*
* Optionally, any of the filename format above can be prepended with relative or absolute URL that
* ends with `/`.
*
*
* ## Manual Bootstrap
* Using auto-bootstrap is a handy way to start using <angular/>, but advanced users who want more
* control over the initialization process might prefer to use manual bootstrap instead.
*
* The best way to get started with manual bootstraping is to look at the magic behind `ng:autobind`
* by writing out each step of the autobind process explicitly. Note that the following code is
* equivalent to the code in the previous section.
*
* <pre>
<!doctype html>
<html xmlns:ng="http://angularjs.org">
<head>
<script type="text/javascript" src="http://code.angularjs.org/angular-0.9.3.min.js"
ng:autobind></script>
<script type="text/javascript">
(angular.element(document).ready(function() {
angular.compile(document)();
})(document);
</script>
</head>
<body>
Hello {{'World'}}!
</body>
</html>
* </pre>
*
* This is the sequence that your code should follow if you're bootstrapping angular on your own:
*
* * After the page is loaded, find the root of the HTML template, which is typically the root of
* the document.
* * Run the HTML compiler, which converts the templates into an executable, bi-directionally bound
* application.
*
*
* ##XML Namespace
* *IMPORTANT:* When using <angular/> you must declare the ng namespace using the xmlns tag. If you
* don't declare the namespace, Internet Explorer does not render widgets properly.
*
* <pre>
* <html xmlns:ng="http://angularjs.org">
* </pre>
*
*
* ## Create your own namespace
* If you want to define your own widgets, you must create your own namespace and use that namespace
* to form the fully qualified widget name. For example, you could map the alias `my` to your domain
* and create a widget called my:widget. To create your own namespace, simply add another xmlsn tag
* to your page, create an alias, and set it to your unique domain:
*
* <pre>
* <html xmlns:ng="http://angularjs.org" xmlns:my="http://mydomain.com">
* </pre>
*
*
* ## Global Object
* The <angular/> script creates a single global variable `angular` in the global namespace. All
* APIs are bound to fields of this global object.
*

* @returns {function([scope][, cloneAttachFn])} a template function which is used to bind template
* (a DOM element/tree) to a scope. Where:
*
* * `scope` - A {@link angular.scope scope} to bind to. If none specified, then a new
* root scope is created.
* * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
* `template` and call the `cloneAttachFn` function allowing the caller to attach the
* cloned elements to the DOM document at the approriate place. The `cloneAttachFn` is
* called as: <br/> `cloneAttachFn(clonedElement, scope)` where:
*
* * `clonedElement` - is a clone of the original `element` passed into the compiler.
* * `scope` - is the current scope with which the linking function is working with.
*
* Calling the template function returns the scope to which the element is bound to. It is either
* the same scope as the one passed into the template function, or if none were provided it's the
* newly create scope.
*
* If you need access to the bound view, there are two ways to do it:
*
* - If you are not asking the linking function to clone the template, create the DOM element(s)
* before you send them to the compiler and keep this reference around.
* <pre>
* var view = angular.element('<p>{{total}}</p>'),
* scope = angular.compile(view)();
* </pre>
*
* - if on the other hand, you need the element to be cloned, the view reference from the original
* example would not point to the clone, but rather to the original template that was cloned. In
* this case, you can access the clone via the cloneAttachFn:
* <pre>
* var original = angular.element('<p>{{total}}</p>'),
* scope = someParentScope.$new(),
* clone;
*
* angular.compile(original)(scope, function(clonedElement, scope) {
* clone = clonedElement;
* //attach the clone to DOM document at the right place
* });
*
* //now we have reference to the cloned DOM via `clone`
* </pre>

/**
* @workInProgress
* @ngdoc overview
* @name angular.scope
*
* @description
* Scope is a JavaScript object and the execution context for expressions. You can think about
* scopes as JavaScript objects that have extra APIs for registering watchers. A scope is the model
* in the model-view-controller design pattern.
*
* A few other characteristics of scopes:
*
* - Scopes can be nested. A scope (prototypically) inherits properties from its parent scope.
* - Scopes can be attached (bound) to the HTML DOM tree (the view).
* - A scope {@link angular.scope.$become becomes} `this` for a controller.
* - A scope's {@link angular.scope.$eval $eval} is used to update its view.
* - Scopes can {@link angular.scope.$watch watch} properties and fire events.
*
* # Basic Operations
* Scopes can be created by calling {@link angular.scope() angular.scope()} or by compiling HTML.
*
* {@link angular.widget Widgets} and data bindings register listeners on the current scope to be
* notified of changes to the scope state. When notified, these listeners push the updated state
* through to the DOM.
*
* Here is a simple scope snippet to show how you can interact with the scope.
* <pre>
var scope = angular.scope();
scope.salutation = 'Hello';
scope.name = 'World';
expect(scope.greeting).toEqual(undefined);
scope.$watch('name', function(){
this.greeting = this.salutation + ' ' + this.name + '!';
});
expect(scope.greeting).toEqual('Hello World!');
scope.name = 'Misko';
// scope.$eval() will propagate the change to listeners
expect(scope.greeting).toEqual('Hello World!');
scope.$eval();
expect(scope.greeting).toEqual('Hello Misko!');
* </pre>
*
* # Inheritance
* A scope can inherit from a parent scope, as in this example:
* <pre>
var parent = angular.scope();
var child = angular.scope(parent);
parent.salutation = "Hello";
child.name = "World";
expect(child.salutation).toEqual('Hello');
child.salutation = "Welcome";
expect(child.salutation).toEqual('Welcome');
expect(parent.salutation).toEqual('Hello');
* </pre>
*
* # Dependency Injection
* Scope also acts as a simple dependency injection framework.
*
* **TODO**: more info needed
*
* # When scopes are evaluated
* Anyone can update a scope by calling its {@link angular.scope.$eval $eval()} method. By default
* angular widgets listen to user change events (e.g. the user enters text into a text field), copy
* the data from the widget to the scope (the MVC model), and then call the `$eval()` method on the
* root scope to update dependents. This creates a spreadsheet-like behavior: the bound views update
* immediately as the user types into the text field.
*
* Similarly, when a request to fetch data from a server is made and the response comes back, the
* data is written into the model and then $eval() is called to push updates through to the view and
* any other dependents.
*
* Because a change in the model that's triggered either by user input or by server response calls
* `$eval()`, it is unnecessary to call `$eval()` from within your controller. The only time when
* calling `$eval()` is needed is when implementing a custom widget or service.
*
* Because scopes are inherited, the child scope `$eval()` overrides the parent `$eval()` method.
* So to update the whole page you need to call `$eval()` on the root scope as `$root.$eval()`.
*
* Note: A widget that creates scopes (i.e. {@link angular.widget.@ng:repeat ng:repeat}) is
* responsible for forwarding `$eval()` calls from the parent to those child scopes. That way,
* calling $eval() on the root scope will update the whole page.
*
*
* @TODO THESE PARAMS AND RETURNS ARE NOT RENDERED IN THE TEMPLATE!! FIX THAT!
* @param {Object} parent The scope that should become the parent for the newly created scope.
* @param {Object.<string, function()>=} providers Map of service factory which need to be provided
* for the current scope. Usually {@link angular.service}.
* @param {Object.<string, *>=} instanceCache Provides pre-instantiated services which should
* append/override services provided by `providers`.
* @returns {Object} Newly created scope.
*
*
* @example
* This example demonstrates scope inheritance and property overriding.
*
* In this example, the root scope encompasses the whole HTML DOM tree. This scope has `salutation`,
* `name`, and `names` properties. The {@link angular.widget@ng:repeat ng:repeat} creates a child
* scope, one for each element in the names array. The repeater also assigns $index and name into
* the child scope.
*
* Notice that:
*
* - While the name is set in the child scope it does not change the name defined in the root scope.
* - The child scope inherits the salutation property from the root scope.
* - The $index property does not leak from the child scope to the root scope.
*

<li ng:repeat="name in names">

* - applying the class's initialization function to the scope instance (without using the new
* operator)
*
* That makes the scope be a `this` for the given class's methods — effectively an instance of
* the given class with additional (scope) stuff. A scope can later `$become` another class.
*
* `$become` gets used to make the current scope act like an instance of a controller class.
* This allows for use of a controller class in two ways.
*
* - as an ordinary JavaScript class for standalone testing, instantiated using the new
* operator, with no attached view.
* - as a controller for an angular model stored in a scope, "instantiated" by
* `scope.$become(ControllerClass)`.
*
* Either way, the controller's methods refer to the model variables like `this.name`. When
* stored in a scope, the model supports data binding. When bound to a view, {{name}} in the
* HTML template refers to the same variable.

*
* The inject function can be used for retrieving service instances or for calling any function

* creates an injection function automatically for the root scope and it is available as
* {@link angular.scope.$service $service}.

* @param {Object.<string, function()>=} [providers=angular.service] Map of provider (factory)
* function.
* @param {Object.<string, function()>=} [cache={}] Place where instances are saved for reuse. Can
* also be used to override services speciafied by `providers` (useful in tests).
* @returns
* {function()} Injector function: `function(value, scope, args...)`:
*
* * `value` - `{string|array|function}`
* * `scope(optional=rootScope)` - optional function "`this`" when `value` is type `function`.
* * `args(optional)` - optional set of arguments to pass to function after injection arguments.
* (also known as curry arguments or currying).
*
* #Return value of `function(value, scope, args...)`
* The injector function return value depended on the type of `value` argument:
*
* * `string`: return an instance for the injection key.
* * `array` of keys: returns an array of instances for those keys. (see `string` above.)
* * `function`: look at `$inject` property of function to determine instances to inject
* and then call the function with instances and `scope`. Any additional arguments
* (`args`) are appended to the function arguments.
* * `none`: initialize eager providers.

* string. All strings or objects with string properties in `array` that contain this string
* will be returned. The predicate can be negated by prefixing the string with `!`.
*
* - `Object`: A pattern object can be used to filter specific properties on objects contained
* by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
* which have property `name` containing "M" and property `phone` containing "1". A special
* property name `$` can be used (as in `{$:"text"}`) to accept a match against any
* property of the object. That's equivalent to the simple substring match with a `string`
* as described above.

* Prevents the input from getting escaped by angular. By default the input is sanitized and

*
* The input is sanitized by parsing the html into tokens. All safe tokens (from a whitelist) are

* it into the returned string, however since our parser is more strict than a typical browser
* parser, it's possible that some obscure input, which would be recognized as valid HTML by a
* browser, won't make it through the sanitizer.
*
* If you hate your users, you may call the filter with optional 'unsafe' argument, which bypasses
* the html sanitizer, but makes your application vulnerable to XSS and other attacks. Using this
* option is strongly discouraged and should be used only if you absolutely trust the input being
* filtered and you can't get the content through the sanitizer.

* Index formatter is meant to be used with `select` input widget. It is useful when one needs
* to select from a set of objects. To create pull-down one can iterate over the array of object
* to build the UI. However the value of the pull-down must be a string. This means that when on
* object is selected form the pull-down, the pull-down value is a string which needs to be
* converted back to an object. This conversion from string to on object is not possible, at best
* the converted object is a copy of the original object. To solve this issue we create a pull-down
* where the value strings are an index of the object in the array. When pull-down is selected the
* index can be used to look up the original user object.
*
* @inputType select
* @param {array} array to be used for selecting an object.
* @returns {object} object which is located at the selected position.

* @workInProgress
* @ngdoc service
* @name angular.service.$resource
* @requires $xhr.cache
*
* @description
* A factory which creates a resource object that lets you interact with
* [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
*
* The returned resource object has action methods which provide high-level behaviors without
* the need to interact with the low level {@link angular.service.$xhr $xhr} service or
* raw XMLHttpRequest.
*
* @param {string} url A parameterized URL template with parameters prefixed by `:` as in
* `/user/:username`.
*
* @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
* `actions` methods.
*
* Each key value in the parameter object is first bound to url template if present and then any
* excess keys are appended to the url search query after the `?`.
*
* Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in
* URL `/path/greet?salutation=Hello`.
*
* If the parameter value is prefixed with `@` then the value of that parameter is extracted from
* the data object (useful for non-GET operations).
*
* @param {Object.<Object>=} actions Hash with declaration of custom action that should extend the
* default set of resource actions. The declaration should be created in the following format:
*
* {action1: {method:?, params:?, isArray:?, verifyCache:?},
* action2: {method:?, params:?, isArray:?, verifyCache:?},
* ...}
*
* Where:
*
* - `action` – {string} – The name of action. This name becomes the name of the method on your
* resource object.
* - `method` – {string} – HTTP request method. Valid methods are: `GET`, `POST`, `PUT`, `DELETE`,
* and `JSON` (also known as JSONP).
* - `params` – {object=} – Optional set of pre-bound parameters for this action.
* - isArray – {boolean=} – If true then the returned object for this action is an array, see
* `returns` section.
* - verifyCache – {boolean=} – If true then whenever cache hit occurs, the object is returned and
* an async request will be made to the server and the resources as well as the cache will be
* updated when the response is received.
*
* @returns {Object} A resource "class" object with methods for the default set of resource actions
* optionally extended with custom `actions`. The default set contains these actions:
*
* { 'get': {method:'GET'},
* 'save': {method:'POST'},
* 'query': {method:'GET', isArray:true},
* 'remove': {method:'DELETE'},
* 'delete': {method:'DELETE'} };
*
* Calling these methods invoke an {@link angular.service.$xhr} with the specified http method,
* destination and parameters. When the data is returned from the server then the object is an
* instance of the resource class `save`, `remove` and `delete` actions are available on it as
* methods with the `$` prefix. This allows you to easily perform CRUD operations (create, read,
* update, delete) on server-side data like this:
* <pre>
var User = $resource('/user/:userId', {userId:'@id'});
var user = User.get({userId:123}, function(){
user.abc = true;
user.$save();
});
</pre>
*
* It is important to realize that invoking a $resource object method immediately returns an
* empty reference (object or array depending on `isArray`). Once the data is returned from the
* server the existing reference is populated with the actual data. This is a useful trick since
* usually the resource is assigned to a model which is then rendered by the view. Having an empty
* object results in no rendering, once the data arrives from the server then the object is
* populated with the data and the view automatically re-renders itself showing the new data. This
* means that in most case one never has to write a callback function for the action methods.
*
* The action methods on the class object or instance object can be invoked with the following
* parameters:
*
* - HTTP GET "class" actions: `Resource.action([parameters], [callback])`
* - non-GET "class" actions: `Resource.action(postData, [parameters], [callback])`
* - non-GET instance actions: `instance.$action([parameters], [callback])`
*
*
* @example
*
* # Credit card resource
*
* <pre>
// Define CreditCard class
var CreditCard = $resource('/user/:userId/card/:cardId',
{userId:123, cardId:'@id'}, {
charge: {method:'POST', params:{charge:true}}
});
// We can retrieve a collection from the server
var cards = CreditCard.query();
// GET: /user/123/card
// server returns: [ {id:456, number:'1234', name:'Smith'} ];
var card = cards[0];
// each item is an instance of CreditCard
expect(card instanceof CreditCard).toEqual(true);
card.name = "J. Smith";
// non GET methods are mapped onto the instances
card.$save();
// POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
// server returns: {id:456, number:'1234', name: 'J. Smith'};
// our custom method is mapped as well.
card.$charge({amount:9.99});
// POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
// server returns: {id:456, number:'1234', name: 'J. Smith'};
// we can create an instance as well
var newCard = new CreditCard({number:'0123'});
newCard.name = "Mike Smith";
newCard.$save();
// POST: /user/123/card {number:'0123', name:'Mike Smith'}
// server returns: {id:789, number:'01234', name: 'Mike Smith'};
expect(newCard.id).toEqual(789);
* </pre>
*
* The object returned from this function execution is a resource "class" which has "static" method
* for each action in the definition.
*
* Calling these methods invoke `$xhr` on the `url` template with the given `method` and `params`.
* When the data is returned from the server then the object is an instance of the resource type and
* all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
* operations (create, read, update, delete) on server-side data.
<pre>
var User = $resource('/user/:userId', {userId:'@id'});
var user = User.get({userId:123}, function(){
user.abc = true;
user.$save();
});
</pre>
*
* It's worth noting that the callback for `get`, `query` and other method gets passed in the
* response that came from the server, so one could rewrite the above example as:
*
<pre>
var User = $resource('/user/:userId', {userId:'@id'});
User.get({userId:123}, function(u){
u.abc = true;
u.$save();
});
</pre>

* @workInProgress
* @ngdoc service
* @name angular.service.$updateView
* @requires $browser
*
* @description
* Calling `$updateView` enqueues the eventual update of the view. (Update the DOM to reflect the
* model). The update is eventual, since there are often multiple updates to the model which may
* be deferred. The default update delayed is 25 ms. This means that the view lags the model by
* that time. (25ms is small enough that it is perceived as instantaneous by the user). The delay
* can be adjusted by setting the delay property of the service.
*
* <pre>angular.service('$updateView').delay = 10</pre>
*
* The delay is there so that multiple updates to the model which occur sufficiently close
* together can be merged into a single update.
*
* You don't usually call '$updateView' directly since angular does it for you in most cases,
* but there are some cases when you need to call it.
*
* - `$updateView()` called automatically by angular:
* - Your Application Controllers: Your controller code is called by angular and hence
* angular is aware that you may have changed the model.
* - Your Services: Your service is usually called by your controller code, hence same rules
* apply.
* - May need to call `$updateView()` manually:
* - Widgets / Directives: If you listen to any DOM events or events on any third party
* libraries, then angular is not aware that you may have changed state state of the
* model, and hence you need to call '$updateView()' manually.
* - 'setTimeout'/'XHR': If you call 'setTimeout' (instead of {@link angular.service.$defer})
* or 'XHR' (instead of {@link angular.service.$xhr}) then you may be changing the model
* without angular knowledge and you may need to call '$updateView()' directly.
*
* NOTE: if you wish to update the view immediately (without delay), you can do so by calling
* {@link scope.$eval} at any time from your code:
* <pre>scope.$root.$eval()</pre>
*
* In unit-test mode the update is instantaneous and synchronous to simplify writing tests.

* While $xhr service provides nicer api than raw XmlHttpRequest, it is still considered a lower
* level api in angular. For a higher level abstraction that utilizes `$xhr`, please check out the
* {@link angular.service$resource $resource} service.
*
* # Error handling
* All XHR responses with response codes other then `2xx` are delegated to
* {@link angular.service.$xhr.error $xhr.error}. The `$xhr.error` can intercept the request
* and process it in application specific way, or resume normal execution by calling the
* request callback method.
*
* # Security Considerations
* When designing web applications your design needs to consider security threats from
* {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
* JSON Vulnerability} and {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF}.
* Both server and the client must cooperate in order to eliminate these threats. Angular comes
* pre-configured with strategies that address these issues, but for this to work backend server
* cooperation is required.
*
* ## JSON Vulnerability Protection
* A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
* JSON Vulnerability} allows third party web-site to turn your JSON resource URL into
* {@link http://en.wikipedia.org/wiki/JSON#JSONP JSONP} request under some conditions. To
* counter this your server can prefix all JSON requests with following string `")]}',\n"`.
* Angular will automatically strip the prefix before processing it as JSON.
*
* For example if your server needs to return:
* <pre>
* ['one','two']
* </pre>
*
* which is vulnerable to attack, your server can return:
* <pre>
* )]}',
* ['one','two']
* </pre>
*
* angular will strip the prefix, before processing the JSON.
*
*
* ## Cross Site Request Forgery (XSRF) Protection
* {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which an
* unauthorized site can gain your user's private data. Angular provides following mechanism to
* counter XSRF. When performing XHR requests, the $xhr service reads a token from a cookie
* called `XSRF-TOKEN` and sets it as the HTTP header `X-XSRF-TOKEN`. Since only JavaScript that
* runs on your domain could read the cookie, your server can be assured that the XHR came from
* JavaScript running on your domain.
*
* To take advantage of this, your server needs to set a token in a JavaScript readable session
* cookie called `XSRF-TOKEN` on first HTTP GET request. On subsequent non-GET requests the server
* can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure that only
* JavaScript running on your domain could have read the token. The token must be unique for each
* user and must be verifiable by the server (to prevent the JavaScript making up its own tokens).
* We recommend that the token is a digest of your site's authentication cookie with
* {@link http://en.wikipedia.org/wiki/Rainbow_table salt for added security}.
*
* @param {string} method HTTP method to use. Valid values are: `GET`, `POST`, `PUT`, `DELETE`, and
* `JSON`. `JSON` is a special case which causes a
* [JSONP](http://en.wikipedia.org/wiki/JSON#JSONP) cross domain request using script tag
* insertion.
* @param {string} url Relative or absolute URL specifying the destination of the request. For
* `JSON` requests, `url` should include `JSON_CALLBACK` string to be replaced with a name of an
* angular generated callback function.
* @param {(string|Object)=} post Request content as either a string or an object to be stringified
* as JSON before sent to the server.
* @param {function(number, (string|Object))} callback A function to be called when the response is
* received. The callback will be called with:
*
* - {number} code [HTTP status code](http://en.wikipedia.org/wiki/List_of_HTTP_status_codes) of
* the response. This will currently always be 200, since all non-200 responses are routed to
* {@link angular.service.$xhr.error} service.
* - {string|Object} response Response object as string or an Object if the response was in JSON
* format.

* @name angular.directive.ng:bind-attr
*
* @description
* The `ng:bind-attr` attribute specifies that {@link guide.data-binding databindings} should be
* created between element attributes and given expressions. Unlike `ng:bind` the `ng:bind-attr`
* contains a JSON key value pairs representing which attributes need to be mapped to which
* {@link guide.expression expressions}.
*
* You don’t usually write the `ng:bind-attr` in the HTML since embedding
* <tt ng:non-bindable>{{expression}}</tt> into the attribute directly as the attribute value is
* preferred. The attributes get translated into `<span ng:bind-attr="{attr:expression}"/>` at
* compile time.
*
* This HTML snippet is preferred way of working with `ng:bind-attr`
* <pre>
* <a href="http://www.google.com/search?q={{query}}">Google</a>
* </pre>
*
* The above gets translated to bellow during bootstrap time.
* <pre>
* <a ng:bind-attr='{"href":"http://www.google.com/search?q={{query}}"}'>Google</a>
* </pre>
*
* @element ANY
* @param {string} attribute_json a JSON key-value pairs representing
* the attributes to replace. Each key matches the attribute
* which needs to be replaced. Each value is a text template of
* the attribute with embedded
* <tt ng:non-bindable>{{expression}}</tt>s. Any number of
* key-value pairs can be specified.
*
* @example
* Try it here: enter text in text box and click Google.

* with `ng:repeat-index` attribute starting from 0. Each template instance gets its own scope where
* the given loop variable is set to the current collection item and `$index` is set to the item
* index or key.
*
* There are special properties exposed on the local scope of each template instance:
*
* * `$index` – `{number}` – iterator offset of the repeated element (0..length-1)
* * `$position` – {string} – position of the repeated element in the iterator. One of: `'first'`,
* `'middle'` or `'last'`.
*
* NOTE: `ng:repeat` looks like a directive, but is actually an attribute widget.
*
* @element ANY
* @param {string} repeat_expression The expression indicating how to enumerate a collection. Two
* formats are currently supported:
*
* * `variable in expression` – where variable is the user defined loop variable and `expression`
* is a scope expression giving the collection to enumerate.
*
* For example: `track in cd.tracks`.
* * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
* and `expression` is the scope expression giving the collection to enumerate.
*
* For example: `(name, age) in {'adam':10, 'amalie':12}`.
*
* @example
* This example initializes the scope to a list of names and
* than uses `ng:repeat` to display every person.

* @ngdoc widget
* @name angular.widget.ng:view
*
* @description
* # Overview
* `ng:view` is a widget that complements the {@link angular.service.$route $route} service by
* including the rendered template of the current route into the main layout (`index.html`) file.
* Every time the current route changes, the included view changes with it according to the
* configuration of the `$route` service.
*
* This widget provides functionality similar to {@link angular.service.ng:include ng:include} when
* used like this:
*
* <ng:include src="$route.current.template" scope="$route.current.scope"></ng:include>
*
*
* # Advantages
* Compared to `ng:include`, `ng:view` offers these advantages:
*
* - shorter syntax
* - more efficient execution
* - doesn't require `$route` service to be available on the root scope
*
*
* @example
<doc:example>
<doc:source>

$route.when('/overview', {controller: OverviewCtrl, template: 'guide.overview.html'});
$route.when('/bootstrap', {controller: BootstrapCtrl, template: 'guide.bootstrap.html'});

* @description
* __Version:__ 0.8.1
*
* ## Install
*
* #### Bower
* ```text
* bower install angular-data
* ```
*
* Load `dist/angular-data.js` or `dist/angular-data.min.js` onto your web page after Angular.js.
*
* #### Npm
* ```text
* npm install angular-data
* ```
*
* Load `dist/angular-data.js` or `dist/angular-data.min.js` onto your web page after Angular.js.
*
* #### Manual download
* Download angular-data.0.8.1.js from the [Releases](https://github.com/jmdobry/angular-data/releases)
* section of the angular-data GitHub project.
*
* ## Load into Angular
* Your Angular app must depend on the module `"angular-data.DS"` in order to use angular-data. Loading
* angular-data into your app allows you to inject the following:
*
* - `DS`
* - `DSHttpAdapter`
* - `DSUtils`
* - `DSErrors`
*
* [DS](/documentation/api/api/DS) is the Data Store itself, which you will inject often.
* [DSHttpAdapter](/documentation/api/api/DSHttpAdapter) is useful as a wrapper for `$http` and is configurable.
* [DSUtils](/documentation/api/api/DSUtils) has some useful utility methods.
* [DSErrors](/documentation/api/api/DSErrors) provides references to the various errors thrown by the data store.
