5	 * All of the code for your public-facing JavaScript source
6	 * should reside in this file.
7	 *
8	 * Note: It has been assumed you will write jQuery code here, so the
9	 * $ function reference has been prepared for usage within the scope
10	 * of this function.
11	 *
12	 * This enables you to define handlers, for when the DOM is ready:
13	 *
14	 * $(function() {
15	 *
16	 * });
17	 *
18	 * When the window is loaded:
19	 *
20	 * $( window ).load(function() {
21	 *
22	 * });
23	 *
24	 * ...and/or other possibilities.
25	 *
26	 * Ideally, it is not considered best practise to attach more than a
27	 * single DOM-ready or window-load handler for a particular page.
28	 * Although scripts in the WordPress core, Plugins and Themes may be
29	 * practising this, we should strive to set a better example in our own work.
