     * A jQuery plugin that detects if form fields have been modified before navigating away from the page. If fields have
     * been modified the user will be confronted with a dialog that will give him the option to leave the page and
     * lose his/her changes or to cancel.
     *
     * The plugin makes use of jQuery "live" events, which enables the plugin to include fields that are added to the DOM
     * by JavaScript.
     *
     * Please note that modified hidden fields will NOT be detected.
