*
* - `chunkSize` - size of generated data chunks (16K by default)
* - `raw` (Boolean) - do raw deflate
* - `gzip` (Boolean) - create gzip wrapper
* - `to` (String) - if equal to 'string', then result will be "binary string"

* - `header` (Object) - custom header for gzip
* - `text` (Boolean) - true if compressed data believed to be text
* - `time` (Number) - modification time, unix timestamp
* - `os` (Number) - operation system code
* - `extra` (Array) - array of bytes with extra data (max 65536)
* - `name` (String) - file name (binary string)

*
* Sends input data to deflate pipe, generating [[Deflate#onData]] calls with
* new compressed chunks. Returns `true` on success. The last data block must have
* mode Z_FINISH (or `true`). That will flush internal pending buffers and call
* [[Deflate#onEnd]]. For interim explicit flushes (without ending the stream) you

*
* On fail call [[Deflate#onEnd]] with error code and return false.
*
* We strongly recommend to use `Uint8Array` on input for best speed (output
* array format is detected automatically). Also, don't skip last param and always
* use the same type in your code (boolean or number). That will improve JS speed.
*
* For regular `Array`-s make sure all elements are [0..255].

Decode literal, length, and distance codes and write out the resulting
literal and match bytes until either not enough input or output is
available, an end-of-block is encountered, or a data error is encountered.
When large enough input and output buffers are supplied to inflate(), for
example, a 16K input buffer and a 64K output buffer, more than 95% of the
inflate execution time is spent in this routine.
Entry assumptions:
state.mode === LEN
strm.avail_in >= 6
strm.avail_out >= 258
start >= strm.avail_out
state.bits < 8
On return, state.mode is one of:
LEN -- ran out of enough output space or enough available input
TYPE -- reached end of block code, inflate() to interpret next block
BAD -- error in block data
Notes:
- The maximum input bits used by a length/distance pair is 15 bits for the
length code, 5 bits for the length extra, 15 bits for the distance code,
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
Therefore if strm.avail_in >= 6, then there is enough input to avoid
checking for available input while decoding.
- The maximum bytes that a single length/distance pair can output is 258
bytes, which is the maximum length that can be coded. inflate_fast()
requires strm.avail_out >= 258 for each loop to avoid checking for
output space.

when a window is already in use, or when output has been written during this
inflate call, but the end of the deflate stream has not been reached yet.
It is also called to create a window for dictionary data when a dictionary
is loaded.
Providing output buffers larger than 32K to inflate() should provide a speed
advantage, since only the last 32K of output is copied to the sliding window
upon return from inflate(), and since all distances after the first 32K of
output will fall in the output data, making match copies simpler and faster.
The advantage may be dependent on the size of the processor's data caches.

Process a set of code lengths to create a canonical Huffman code. The
code lengths are lens[0..codes-1]. Each length corresponds to the
symbols 0..codes-1. The Huffman code is generated by first sorting the
symbols by length from short to long, and retaining the symbol order
for codes with equal lengths. Then the code starts with all zero bits
for the first code of the shortest length, and the codes are integer
increments for the same length, and zeros are appended as the length
increases. For the deflate format, these bits are stored backwards
from their more natural integer increment ordering, and so when the
decoding tables are built in the large loop below, the integer codes
are incremented backwards.
This routine assumes, but does not check, that all of the entries in
lens[] are in the range 0..MAXBITS. The caller must assure this.
1..MAXBITS is interpreted as that code length. zero means that that
symbol does not occur in this code.
The codes are sorted by computing a count of codes for each length,
creating from that a table of starting indices for each length in the
sorted table, and then entering the symbols in order in the sorted
table. The sorted table is work[], with that space being provided by

Create and fill in decoding tables. In this loop, the table being
filled is at next and has curr index bits. The code being used is huff
with length len. That code is converted to an index by dropping drop
bits off of the bottom. For codes where len is less than drop + curr,
those top drop + curr - len bits are incremented through all values to
fill the table with replicated entries.
root is the number of index bits for the root table. When len exceeds
root, sub-tables are created pointed to by the root entry with an index
of the low root bits of huff. This is saved in low to check for when a
new sub-table should be started. drop is zero when the root table is
being filled, and drop is root when sub-tables are being filled.
When a new sub-table is needed, it is necessary to look ahead in the
code lengths to determine what size sub-table is needed. The length
counts are used for this, and so count[] is decremented as codes are
entered in the tables.
used keeps track of how many table entries have been allocated from the
provided *table space. It is checked for LENS and DIST tables against
the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
the initial root table size constants. See the comments in inftrees.h
for more information.
sym increments through all symbols, and the loop terminates when
all codes of length max, i.e. all codes, have been processed. This
routine permits incomplete codes, so another loop after this one fills
in the rest of the decoding tables with invalid code markers.

* Gesture object
* --------------------

* defaults: {
* mygesture_option: true
* }
* handler: function(type, ev, inst) {
* // trigger gesture event
* inst.trigger(this.name, ev);
* }
* }
* @param {String} name
* this should be the name of the gesture, lowercase
* it is also being used to disable/enable the gesture per instance config.
*
* @param {Number} [index=1000]
* the index of the gesture, where it is going to be in the stack of gestures detection
* like when you build an gesture that depends on the drag gesture, it is a good
* idea to place it after the index of the drag gesture.
*
* @param {Object} [defaults={}]
* the default settings of the gesture. these are added to the instance settings,
* and can be overruled per instance. you can also add the name of the gesture,
* but this is also added by default (and set to true).
*
* @param {Function} handler
* this handles the gesture detection of your custom gesture and receives the
* following arguments:
*
* @param {Object} eventData
* event data containing the following properties:
* timeStamp {Number} time the event occurred
* target {HTMLElement} target element
* touches {Array} touches (fingers, pointers, mouse) on the screen
* pointerType {String} kind of pointer that was used. matches Hammer.POINTER_MOUSE|TOUCH
* center {Object} center position of the touches. contains pageX and pageY
* deltaTime {Number} the total time of the touches in the screen
* deltaX {Number} the delta on x axis we haved moved
* deltaY {Number} the delta on y axis we haved moved
* velocityX {Number} the velocity on the x
* velocityY {Number} the velocity on y
* angle {Number} the angle we are moving
* direction {String} the direction we are moving. matches Hammer.DIRECTION_UP|DOWN|LEFT|RIGHT
* distance {Number} the distance we haved moved
* scale {Number} scaling of the touches, needs 2 touches
* rotation {Number} rotation of the touches, needs 2 touches *
* eventType {String} matches Hammer.EVENT_START|MOVE|END
* srcEvent {Object} the source event, like TouchStart or MouseDown *
* startEvent {Object} contains the same properties as above,
* but from the first touch. this is used to calculate
* distances, deltaTime, scaling etc
*
* @param {Hammer.Instance} inst
* the instance we are doing the detection for. you can get the options from
* the inst.options object and trigger the gesture event by calling inst.trigger
*
*
* Handle gestures
* --------------------
* inside the handler you can get/set Hammer.detection.current. This is the current
* detection session. It has the following properties
* @param {String} name
* contains the name of the gesture we have detected. it has not a real function,
* only to check in other gestures if something is detected.
* like in the drag gesture we set it to 'drag' and in the swipe gesture we can
* check if the current gesture is 'drag' by accessing Hammer.detection.current.name
*
* @readonly
* @param {Hammer.Instance} inst
* the instance we do the detection for
*
* @readonly
* @param {Object} startEvent
* contains the properties of the first gesture detection in this session.
* Used for calculations about timing, distance, etc.
*
* @readonly
* @param {Object} lastEvent
* contains all the properties of the last gesture detect in this session.
*
* after the gesture detection session has been completed (user has released the screen)
* the Hammer.detection.current object is copied into Hammer.detection.previous,
* this is usefull for gestures like doubletap, where you need to know if the
* previous gesture was a tap
*
* options that have been set by the instance can be received by calling inst.options
*
* You can trigger a gesture event by calling inst.trigger("mygesture", event).
* The first param is the name of your gesture, the second the event argument
*
*
* Register gestures
* --------------------
* When an gesture is added to the Hammer.gestures object, it is auto registered
* at the setup of the first Hammer instance. You can also call Hammer.detection.register
* manually and pass your gesture object as a param
*

* WireClient Interface
* --------------------
*
* This file exposes a get/put/delete interface on top of XMLHttpRequest.
* It requires to be configured with parameters about the remotestorage server to
* connect to.
* Each instance of WireClient is always associated with a single remotestorage
* server and access token.
*
* Usually the WireClient instance can be accessed via `remoteStorage.remote`.
*
* This is the get/put/delete interface:
*
* - #get() takes a path and optionally a ifNoneMatch option carrying a version
* string to check. It returns a promise that will be fulfilled with the HTTP
* response status, the response body, the MIME type as returned in the
* 'Content-Type' header and the current revision, as returned in the 'ETag'
* header.
* - #put() takes a path, the request body and a content type string. It also
* accepts the ifMatch and ifNoneMatch options, that map to the If-Match and
* If-None-Match headers respectively. See the remotestorage-01 specification
* for details on handling these headers. It returns a promise, fulfilled with
* the same values as the one for #get().
* - #delete() takes a path and the ifMatch option as well. It returns a promise
* fulfilled with the same values as the one for #get().
*
* In addition to this, the WireClient has some compatibility features to work with
* remotestorage 2012.04 compatible storages. For example it will cache revisions
* from folder listings in-memory and return them accordingly as the "revision"
* parameter in response to #get() requests. Similarly it will return 404 when it
* receives an empty folder listing, to mimic remotestorage-01 behavior. Note
* that it is not always possible to know the revision beforehand, hence it may
* be undefined at times (especially for caching-roots).

* >>> Math.uuid(15) // 15 character ID (default base=62)
* "VcydxgltxrVZSTV"
*
* // Two arguments - returns ID of the specified length, and radix. (Radix must be <= 62)
* >>> Math.uuid(8, 2) // 8 character ID (base=2)
* "01001010"
* >>> Math.uuid(8, 10) // 8 character ID (base=10)
* "47473046"

* Event: change
*
* Emitted when a node changes
*
* Arguments:
* event - Event object containing information about the changed node
*
* (start code)
* {
* path: path, // Absolute path of the changed node, from the storage root
* relativePath: relativePath, // Path of the changed node, relative to this baseclient's scope root
* origin: 'window', 'local', 'remote', or 'conflict' // emitted by user action within the app, local data store, remote sync, or versioning conflicts
* oldValue: oldBody, // Old body of the changed node (local version in conflicts; undefined if creation)
* newValue: newBody, // New body of the changed node (remote version in conflicts; undefined if deletion)
* lastCommonValue: lastCommonValue, //most recent known common ancestor body of 'yours' and 'theirs' in case of conflict
* oldContentType: oldContentType, // Old contentType of the changed node ('yours' for conflicts; undefined if creation)
* newContentType: newContentType, // New contentType of the changed node ('theirs' for conflicts; undefined if deletion)
* lastCommonContentType: lastCommonContentType // Most recent known common ancestor contentType of 'yours' and 'theirs' in case of conflict
* }
* (end code)
*
* Example of an event with origin 'local' (fired on page load):
*
* (start code)
* {
* path: '/public/design/color.txt',
* relativePath: 'color.txt',
* origin: 'local',
* oldValue: undefined,
* newValue: 'white',
* oldContentType: undefined,
* newContentType: 'text/plain'
* }
* (end code)
*
* Example of a conflict:
* Say you changed 'color.txt' from 'white' to 'blue'; if you have set `RemoteStorage.config.changeEvents.window` to `true`,
* then you will receive:
*
* (start code)
* {
* path: '/public/design/color.txt',
* relativePath: 'color.txt',
* origin: 'window',
* oldValue: 'white',
* newValue: 'blue',
* oldContentType: 'text/plain',
* newContentType: 'text/plain'
* }
* (end code)
*
* But when this change is pushed out by asynchronous synchronization, this change may rejected by the
* server, if the remote version has in the meantime changed from 'white' to for instance 'red'; this will then lead to a change
* event with origin 'conflict' (usually a few seconds after the event with origin 'window', if you had that activated). Note
* that since you already changed it from 'white' to 'blue' in the local version a few seconds ago, `oldValue` is now your local
* value of 'blue':
*
* (start code)
* {
* path: '/public/design/color.txt',
* relativePath: 'color.txt',
* origin: 'conflict',
* oldValue: 'blue',
* newValue: 'red',
* lastCommonValue: 'white',
* oldContentType: 'text/plain,
* newContentType: 'text/plain'
* lastCommonContentType: 'text/plain'
* }
* (end code)
*
* In practice, you should always redraw your views to display the content of the `newValue` field when a change event is received,
* regardless of its origin. Events with origin 'local' are fired conveniently during the page load, so that you can fill your views
* when the page loads. Events with origin 'window' are fired whenever you change a value by calling a method on the baseClient;
* these are disabled by default. Events with origin 'remote' are fired when remote changes are discovered during sync (only for caching
* startegies 'SEEN' and 'ALL'). Events with origin 'conflict' are fired when a conflict occurs while pushing out your local changes to
* the remote store in asynchronous synchronization (see example above).

* Method: storeObject

*
* Parameters:
*
* type - unique type of this object within this module. See description below.
* path - path relative to the module root.
* object - an object to be saved to the given node. It must be serializable as JSON.
*
* Returns:
* A promise to store the object. The promise fails with a ValidationError, when validations fail.
*
*
* What about the type?:
*
* A great thing about having data on the web, is to be able to link to
* it and rearrange it to fit the current circumstances. To facilitate
* that, eventually you need to know how the data at hand is structured.
* For documents on the web, this is usually done via a MIME type. The
* MIME type of JSON objects however, is always application/json.
* To add that extra layer of "knowing what this object is", remoteStorage
* aims to use <JSON-LD at http://json-ld.org/>.
* A first step in that direction, is to add a *@context attribute* to all
* JSON data put into remoteStorage.
* Now that is what the *type* is for.
*
* Within remoteStorage.js, @context values are built using three components:
* http://remotestorage.io/spec/modules/ - A prefix to guarantee uniqueness
* the module name - module names should be unique as well
* the type given here - naming this particular kind of object within this module
*
* In retrospect that means, that whenever you introduce a new "type" in calls to
* storeObject, you should make sure that once your code is in the wild, future
* versions of the code are compatible with the same JSON structure.
*
* How to define types?:
*
* See <declareType> for examples.

* Summary of `ReactEventEmitter` event handling:
*
* - Top-level delegation is used to trap native browser events. We normalize
* and de-duplicate events to account for browser quirks.
*
* - Forward these native events (with the associated top-level type used to
* trap it) to `EventPluginHub`, which in turn will ask plugins if they want
* to extract any synthetic events.
*
* - The `EventPluginHub` will then process each event by annotating them with
* "dispatches", a sequence of listeners and IDs that care about that event.
*
* - The `EventPluginHub` then dispatches the events.

Implementation Summary
1. Enforce API surface and semantic compatibility with 1.9.x branch
2. Improve the module's maintainability by reducing the storage

3. Use the same single mechanism to support "private" and "user" data.
4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
5. Avoid exposing implementation details on user objects (eg. expando properties)
6. Provide a clear path for implementation upgrade to WeakMap in 2014
