* 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
* @param Element|jQuery context (optional) A DOM Element, Document or jQuery to use as context

* 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.
*
