/**
- * A common wrapper for making XMLHttpRequests
+ * Load a remote page using an HTTP request.
+ *
+ * This is jQuery's low-level AJAX implementation. See $.get, $.post etc. for
+ * higher-level abstractions that are often easier to understand and use,
+ * but don't offer as much functionality (such as error callbacks).
+ *
+ * $.ajax() returns the XMLHttpRequest that it creates. In most cases you won't
+ * need that object to manipulate directly, but it is available if you need to
+ * abort the request manually.
+ *
+ * '''Note:''' If you specify the dataType option described below, make sure
+ * the server sends the correct MIME type in the response (eg. xml as "text/xml").
+ * Sending the wrong MIME type can lead to unexpected problems in your script.
+ * See [[Specifying the Data Type for AJAX Requests]] for more information.
+ *
+ * Supported datatypes are (see dataType option):
+ *
+ * "xml": Returns a XML document that can be processed via jQuery.
+ *
+ * "html": Returns HTML as plain text, included script tags are evaluated.
+ *
+ * "script": Evaluates the response as Javascript and returns it as plain text.
+ *
+ * "json": Evaluates the response as JSON and returns a Javascript Object
+ *
+ * $.ajax() takes one argument, an object of key/value pairs, that are
+ * used to initalize and handle the request. These are all the key/values that can
+ * be used:
+ *
+ * (String) url - The URL to request.
+ *
+ * (String) type - The type of request to make ("POST" or "GET"), default is "GET".
+ *
+ * (String) dataType - The type of data that you're expecting back from
+ * the server. No default: If the server sends xml, the responseXML, otherwise
+ * the responseText is passed to the success callback.
+ *
+ * (Boolean) ifModified - Allow the request to be successful only if the
+ * response has changed since the last request. This is done by checking the
+ * Last-Modified header. Default value is false, ignoring the header.
+ *
+ * (Number) timeout - Local timeout in milliseconds to override global timeout, eg. to give a
+ * single request a longer timeout while all others timeout after 1 second.
+ * See $.ajaxTimeout() for global timeouts.
+ *
+ * (Boolean) global - Whether to trigger global AJAX event handlers for
+ * this request, default is true. Set to false to prevent that global handlers
+ * like ajaxStart or ajaxStop are triggered.
+ *
+ * (Function) error - A function to be called if the request fails. The
+ * function gets passed tree arguments: The XMLHttpRequest object, a
+ * string describing the type of error that occurred and an optional
+ * exception object, if one occured.
+ *
+ * (Function) success - A function to be called if the request succeeds. The
+ * function gets passed one argument: The data returned from the server,
+ * formatted according to the 'dataType' parameter.
+ *
+ * (Function) complete - A function to be called when the request finishes. The
+ * function gets passed two arguments: The XMLHttpRequest object and a
+ * string describing the type of success of the request.
+ *
+ * (Object|String) data - Data to be sent to the server. Converted to a query
+ * string, if not already a string. Is appended to the url for GET-requests.
+ * See processData option to prevent this automatic processing.
+ *
+ * (String) contentType - When sending data to the server, use this content-type.
+ * Default is "application/x-www-form-urlencoded", which is fine for most cases.
+ *
+ * (Boolean) processData - By default, data passed in to the data option as an object
+ * other as string will be processed and transformed into a query string, fitting to
+ * the default content-type "application/x-www-form-urlencoded". If you want to send
+ * DOMDocuments, set this option to false.
+ *
+ * (Boolean) async - By default, all requests are sent asynchronous (set to true).
+ * If you need synchronous requests, set this option to false.
+ *
+ * (Function) beforeSend - A pre-callback to set custom headers etc., the
+ * XMLHttpRequest is passed as the only argument.
+ *
+ * @example $.ajax({
+ * type: "GET",
+ * url: "test.js",
+ * dataType: "script"
+ * })
+ * @desc Load and execute a JavaScript file.
+ *
+ * @example $.ajax({
