	/**
	* ajaxSubmit() provides a mechanism for submitting an HTML form using AJAX.
	*
	* ajaxSubmit accepts a single argument which can be either a success callback function
	* or an options Object.  If a function is provided it will be invoked upon successful
	* completion of the submit and will be passed the response from the server.
	* If an options Object is provided, the following attributes are supported:
	*
	*  target:   Identifies the element(s) in the page to be updated with the server response.
	*            This value may be specified as a jQuery selection string, a jQuery object,
	*            or a DOM element.
	*            default value: null
	*
	*  url:      URL to which the form data will be submitted.
	*            default value: value of form's 'action' attribute
	*
	*  type:     The method in which the form data should be submitted, 'GET' or 'POST'.
	*            default value: value of form's 'method' attribute (or 'GET' if none found)
	*
	*  data:     Additional data to add to the request, specified as key/value pairs (see $.ajax).
	*
	*  beforeSubmit:  Callback method to be invoked before the form is submitted.
	*            default value: null
	*
	*  success:  Callback method to be invoked after the form has been successfully submitted
	*            and the response has been returned from the server
	*            default value: null
	*
	*  dataType: Expected dataType of the response.  One of: null, 'xml', 'script', or 'json'
	*            default value: null
	*
	*  semantic: Boolean flag indicating whether data must be submitted in semantic order (slower).
	*            default value: false
	*
	*  resetForm: Boolean flag indicating whether the form should be reset if the submit is successful
	*
	*  clearForm: Boolean flag indicating whether the form should be cleared if the submit is successful
	*
	*
	* The 'beforeSubmit' callback can be provided as a hook for running pre-submit logic or for
	* validating the form data.  If the 'beforeSubmit' callback returns false then the form will
	* not be submitted. The 'beforeSubmit' callback is invoked with three arguments: the form data
	* in array format, the jQuery object, and the options object passed into ajaxSubmit.
	* The form data array takes the following form:
	*
	*     [ { name: 'username', value: 'jresig' }, { name: 'password', value: 'secret' } ]
	*
	* If a 'success' callback method is provided it is invoked after the response has been returned
	* from the server.  It is passed the responseText or responseXML value (depending on dataType).
	* See jQuery.ajax for further details.
	*
	*
	* The dataType option provides a means for specifying how the server response should be handled.
	* This maps directly to the jQuery.httpData method.  The following values are supported:
	*
	*      'xml':    if dataType == 'xml' the server response is treated as XML and the 'success'
	*                   callback method, if specified, will be passed the responseXML value
	*      'json':   if dataType == 'json' the server response will be evaluted and passed to
	*                   the 'success' callback, if specified
	*      'script': if dataType == 'script' the server response is evaluated in the global context
	*
	*
	* Note that it does not make sense to use both the 'target' and 'dataType' options.  If both
	* are provided the target will be ignored.
	*
	* The semantic argument can be used to force form serialization in semantic order.
	* This is normally true anyway, unless the form contains input elements of type='image'.
	* If your form must be submitted with name/value pairs in semantic order and your form
	* contains an input of type='image" then pass true for this arg, otherwise pass false
	* (or nothing) to avoid the overhead for this logic.
	*
	*
	* When used on its own, ajaxSubmit() is typically bound to a form's submit event like this:
	*
	* $("#form-id").submit(function() {
	*     $(this).ajaxSubmit(options);
	*     return false; // cancel conventional submit
	* });
	*
	* When using ajaxForm(), however, this is done for you.
	*
	* @example
	* $('#myForm').ajaxSubmit(function(data) {
	*     alert('Form submit succeeded! Server returned: ' + data);
	* });
	* @desc Submit form and alert server response
	*
	*
	* @example
	* var options = {
	*     target: '#myTargetDiv'
	* };
	* $('#myForm').ajaxSubmit(options);
	* @desc Submit form and update page element with server response
	*
	*
	* @example
	* var options = {
	*     success: function(responseText) {
	*         alert(responseText);
	*     }
	* };
	* $('#myForm').ajaxSubmit(options);
	* @desc Submit form and alert the server response
	*
	*
	* @example
	* var options = {
	*     beforeSubmit: function(formArray, jqForm) {
	*         if (formArray.length == 0) {
	*             alert('Please enter data.');
	*             return false;
	*         }
	*     }
	* };
	* $('#myForm').ajaxSubmit(options);
	* @desc Pre-submit validation which aborts the submit operation if form data is empty
	*
	*
	* @example
	* var options = {
	*     url: myJsonUrl.php,
	*     dataType: 'json',
	*     success: function(data) {
	*        // 'data' is an object representing the the evaluated json data
	*     }
	* };
	* $('#myForm').ajaxSubmit(options);
	* @desc json data returned and evaluated
	*
	*
	* @example
	* var options = {
	*     url: myXmlUrl.php,
	*     dataType: 'xml',
	*     success: function(responseXML) {
	*        // responseXML is XML document object
	*        var data = $('myElement', responseXML).text();
	*     }
	* };
	* $('#myForm').ajaxSubmit(options);
	* @desc XML data returned from server
	*
	*
	* @example
	* var options = {
	*     resetForm: true
	* };
	* $('#myForm').ajaxSubmit(options);
	* @desc submit form and reset it if successful
	*
	* @example
	* $('#myForm).submit(function() {
	*    $(this).ajaxSubmit();

	/**
	* ajaxForm() provides a mechanism for fully automating form submission.
	*
	* The advantages of using this method instead of ajaxSubmit() are:
	*
	* 1: This method will include coordinates for <input type="image" /> elements (if the element
	*    is used to submit the form).
	* 2. This method will include the submit element's name/value data (for the element that was
	*    used to submit the form).
	* 3. This method binds the submit() method to the form for you.
	*
	* Note that for accurate x/y coordinates of image submit elements in all browsers
	* you need to also use the "dimensions" plugin (this method will auto-detect its presence).
	*
	* The options argument for ajaxForm works exactly as it does for ajaxSubmit.  ajaxForm merely
	* passes the options argument along after properly binding events for submit elements and
	* the form itself.  See ajaxSubmit for a full description of the options argument.
	*
	*
	* @example
	* var options = {
	*     target: '#myTargetDiv'
	* };
	* $('#myForm').ajaxSForm(options);
	* @desc Bind form's submit event so that 'myTargetDiv' is updated with the server response
	*       when the form is submitted.
	*
	*
	* @example
	* var options = {
	*     success: function(responseText) {
	*         alert(responseText);
	*     }
	* };
	* $('#myForm').ajaxSubmit(options);
	* @desc Bind form's submit event so that server response is alerted after the form is submitted.
	*
	*
	* @example
	* var options = {
	*     beforeSubmit: function(formArray, jqForm) {
	*         if (formArray.length == 0) {
	*             alert('Please enter data.');
	*             return false;
	*         }
	*     }
	* };
	* $('#myForm').ajaxSubmit(options);

	*       is submitted.
