/**
 * This file is generic enough to use on all
 * action forms which require contact with
 * AJAX invokations
 *
 *
 * N.B. This script below just asures that the active
 *      window browser is listening for end use events
 *      and it will prepare a HTTP POST to the desired
 *      AJAX event.
 *      i.e. A "Contact Us" input form, sends off its
 *           input fields to a validation and processing
 *           AJAX script.
 *
 * N.B. This script is expecting to have a return xml tag
 *      named "status"
