  /**
   * 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.
   *
   * 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.
