/**
 * Example of Using HTML_AJAX in proxyless operation
 *
 * This is the simplest way to use HTML_AJAX if your just using grab and replace functions you don't even need a server
 * You need every javascript file except JSON which is optional and is only needed if your using that encoding
 *
 * The proxyless api is provided by Main.js
 *
 * There are 4 main methods and 2 properties to the proxyless api, they all exist as static methods on HTML_AJAX
 *	HTML_AJAX.grab(url)
 *	HTML_AJAX.post(url,payload)
 *	HTML_AJAX.replace(id,url) or HTML_AJAX.replace(id,class,method,arg1,arg2,etc)
 *	HTML_AJAX.call(class,method,callback,arg1,arg2,etc)
 *
 *	HTML_AJAX.defaultServerUrl = 'serverurl';
 *	HTML_AJAX.defaultEncoding = 'Null';
 *
 * The api is demonstrated below, server.php is used for call examples and to load the needed js files
