Note that this option will force crawler to use only one connection - externalDomains : if true crawl the external domains. This option can crawl a lot of different linked domains, default = false. - externalHosts : if true crawl the others hosts on the same domain, default = false. - firstExternalLinkOnly : crawl only the first link found for external domains/hosts. externalHosts or externalDomains should be = true - scripts : if true crawl script tags - links : if true crawl link tags - linkTypes : the type of the links tags to crawl (match to the rel attribute), default : ["canonical", "stylesheet"] - images : if true crawl images - protocols : list of the protocols to crawl, default = ["http", "https"] - timeout : timeout per requests in milliseconds (Default 20000) - retries : number of retries if the request fails (default 3) - retryTimeout : number of milliseconds to wait before retrying (Default 10000) - depthLimit : the depth limit for the crawl - followRedirect : if true, the crawl will not return the 301, it will follow directly the redirection - proxyList : the list of proxies (see the project simple-proxies on npm) - storeModuleName : the npm nodule name used for the store implementation, by default : memory-store - storeParams : the params to pass to the store module when create it. - queueModuleName : the npm module name used for the job queue.

`Notification` constructor. A `Notification` encapsulates information so that it can be broadcast to other objects via a `NotificationCenter`. A notification contains a `name`, `object`, and optional `info` hash. The `name` is a string that uniquely identifies the type of notification. The `object` is any object that the poster of the notification wants to send to the observers (typically, it is the object that posted the notification). The `info` is any related information, if any, contained in an object literal. Examples: new Notification('myClass.interestingEvent', this); new Notification('myClass.otherInterestingEvent', this, { foo: 'bar' }); @param {String} name @param {Object} object @param {Object} info @api public
