/* addDOMLoadEvent: Adds Events To Fire At DOM Load
-------------------------------------------------------*/
/*
 * (c)2006 Jesse Skinner/Dean Edwards/Matthias Miller/John Resig
 * Special thanks to Dan Webb's domready.js Prototype extension
 * and Simon Willison's addLoadEvent
 *
 * For more info, see:

 * http://simon.incutio.com/archive/2004/05/26/addLoadEvent
 * 
 *
 * To use: call addDOMLoadEvent one or more times with functions, ie:
 *
 *    function something() {
 *       // do something
 *    }
 *    addDOMLoadEvent(something);
 *
 *    addDOMLoadEvent(function() {
 *        // do other stuff
 *    });
