 @fileoverview

 Constructor for the AjaxRequest class. 
 
 <br><br>
 Example:
 
 <br><br>
 var ajaxRequest = new AjaxRequest("YOUR_URL");
 
 @class The AjaxRequest object wraps an instance of XMLHttpRequest and provides 
 facilities for setting functions that are called before a request is made
 and after a request returns. By default, AjaxRequest handles the server
 response by simply calling eval(), passing to it the responseText from 
 the XMLHttpRequestObject, of course assuming that the response was 
 generated by Taconite on the server side and that running eval() will 
 update the web page.<br><br>Example Usage:<br><br>var ajaxRequest = new AjaxRequest("YOUR_URL");
 <br>ajaxRequest.addFormElements("form_element_id_attribute_value");
 <br>ajaxRequest.sendRequest();
 
 @constructor
 @param {String} a String repesenting the URL to which the Ajax request
 will be sent.

            value       any JavaScript value, usually an object or array.

            whitelist   an optional that determines how object values are
                        stringified.

            This method produces a JSON text from a JavaScript value.
            There are three possible ways to stringify an object, depending
            on the optional whitelist parameter.

            If an object has a toJSON method, then the toJSON() method will be
            called. The value returned from the toJSON method will be
            stringified.

            Otherwise, if the optional whitelist parameter is an array, then
            the elements of the array will be used to select members of the
            object for stringification.

            Otherwise, if there is no whitelist parameter, then all of the
            members of the object will be stringified.

            Values that do not have JSON representaions, such as undefined or
            functions, will not be serialized. Such values in objects will be
            dropped, in arrays will be replaced with null. JSON.stringify()
            returns undefined. Dates will be stringified as quoted ISO dates.

            Example:

            var text = JSON.stringify(['e', {pluribus: 'unum'}]);
            // text is '["e",{"pluribus":"unum"}]'

        JSON.parse(text, filter)
            This method parses a JSON text to produce an object or
            array. It can throw a SyntaxError exception.

            The optional filter parameter is a function that can filter and
            transform the results. It receives each of the keys and values, and
            its return value is used instead of the original value. If it
            returns what it received, then structure is not modified. If it
            returns undefined then the member is deleted.

            Example:

            // Parse the text. If a key contains the string 'date' then
            // convert the value to a date.

            myData = JSON.parse(text, function (key, value) {
                return key.indexOf('date') >= 0 ? new Date(value) : value;
            });

// replace all simple value tokens with ']' characters. Third, we delete all
