// AMQ Ajax Adapter for Dojo 
// This class provides an adapter interface for the Dojo library to perform
// some of the library-dependent tasks...namely logging and ajax.

/**
 *  Implement this method to make an AJAX call to the AjaxServlet. An
 *  options object will accompany this class and will contain the properties
 *  that describe the details of the AJAX call. The options object will
 *  have the following properties:
 *
 *  - method:  'get' or 'post'
 *  - data:    query data to accompany the post or get.
 *  - success: A callback function that is invoked upon successful
 *             completion of the AJAX call. The parameter is:
 *             - data: The result of the AJAX call. In the case of XML
 *                     data should resolve to a Document element.
 *  - error:   A callback when some type of error occurs. The callback
 *             function's parameters should be:
 *             - xhr:    The XmlHttpRequest object.
 *             - status: A text string of the status.
 *             - ex:     The exception that caused the error.
 *  - headers: An object containing additional headers for the ajax request.
