/**
 * XML_RPC2_Server is the frontend class for exposing PHP functions via XML-RPC. 
 *
 * Exporting a programatic interface via XML-RPC using XML_RPC2 is exceedingly easy:
 *
 * The first step is to assemble all methods you wish to export into a class. You may either
 * create a (abstract) class with exportable methods as static, or use an existing instance
 * of an object.
 *
 * You'll then need to document the methods using PHPDocumentor tags. XML_RPC2 will use the
 * documentation for server introspection. You'll get something like this:
 *
 * <code>
 * class ExampleServer {
 *     /**
 *      * hello says hello
 *      *
 *      * @param string  Name
 *      * @return string Greetings
 *      {@*}
 *     public static function hello($name) 
    {
 *         return "Hello $name";
 *     }
 * }
 * </code>
 *
 * Now, instantiate the server, using the Factory method to select a backend and a call handler for you:
 * <code>
 * require_once 'XML/RPC2/Server.php';
 * $server = XML_RPC2_Server::create('ExampleServer');
 * $server->handleCall();
 * </code>
 *
 * This will create a server exporting all of the 'ExampleServer' class' methods. If you wish to export
 * instance methods as well, pass an object instance to the factory instead:
 * <code>
 * require_once 'XML/RPC2/Server.php';
 * $server = XML_RPC2_Server::create(new ExampleServer());
 * $server->handleCall();
 * </code>
