+ * global function to senbd/retrieve data with the server
+ *
+ * param: the data to be sent or retrieved.
+ *   param will be converted to string, escaping quotes newlines and backslashes if necessary.
+ *   param can be a javascript string, boolean, number, dictionary and array.
+ *       If dictionary or array, it must contain only the above mentioned recognized types.

+ * onSuccesFcn(data, textStatus, jqXHR) OPTIONAL --IF MISSING, NOTHING HAPPENS --
+ *    A function to be called if the request succeeds with the same syntax of jQuery's ajax onSuccess function.
+ *    The function gets passed three arguments
+ *       The data returned from the server, formatted according to the dataType parameter;
+ *       a string describing the status;
+ *       and the jqXHR (in jQuery 1.4.x, XMLHttpRequest) object
+ *
+ * onErrorFcn(jqXHR, textStatus, errorThrown) OPTIONAL. --IF MISSING, THE DEFAULT ERROR DIALOG IS SHOWN--
+ *     A function to be called if the request fails with the same syntax of jQuery ajax onError function..
+ *     The function receives three arguments:
+ *       The jqXHR (in jQuery 1.4.x, XMLHttpRequest) object,
+ *       a string describing the type of error that occurred and
+ *       an optional exception object, if one occurred.
+ *       Possible values for the second argument (besides null) are "timeout", "error", "abort", and "parsererror".
