/**
 * This function accepts a string containing a CSS or
 * basic XPath selector which is then used to match a set of elements.
 *
 * The core functionality of jQuery centers around this function.
 * Everything in jQuery is based upon this, or uses this in some way.
 * The most basic use of this function is to pass in an expression
 * (usually consisting of CSS or XPath), which then finds all matching
 * elements.
 *
 * By default, if no context is specified, $() looks for DOM elements within the context of the
 * current HTML document. If you do specify a context, such as a DOM
 * element or jQuery object, the expression will be matched against
 * the contents of that context.
 *
 * See [[DOM/Traversing/Selectors]] for the allowed CSS/XPath syntax for expressions.
 *
 * @example $("div > p")
 * @desc Finds all p elements that are children of a div element.
 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
 * @result [ <p>two</p> ]
 *
 * @example $("input:radio", document.forms[0])
 * @desc Searches for all inputs of type radio within the first form in the document
 *
 * @example $("div", xml.responseXML)
 * @desc This finds all div elements within the specified XML document.
 *
 * @name $
 * @param String expr An expression to search with

	 * Bind a function to be executed whenever the DOM is ready to be

	 * In a nutshell, this is a solid replacement for using window.onload,

	 * will be called the instant the DOM is ready to be read and manipulated,

	 * There is one argument passed to the ready event handler: A reference to
	 * the jQuery function. You can name that argument whatever you like, and
	 * can therefore stick with the $ alias without risk of naming collisions.
	 * 
	 * Please ensure you have no code in your &lt;body&gt; onload event handler, 
	 * otherwise $(document).ready() may not fire.
	 *
	 * You can have as many $(document).ready events on your page as you like.
	 * The functions are then executed in the order they were added.

	 *   // Your code using failsafe $ alias here...

	/**
	 * 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 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.
	 *
