+ * Setting up the provider:
+ * <pre><code>
+ * var socket = new easyXDM.Socket({
+ * local: "name.html",
+ * onReady: function(){
+ * // you need to wait for the onReady callback before using the socket
+ * socket.postMessage("foo-message");
+ * },
+ * onMessage: function(message, origin) {
+ * alert("received " + message + " from " + origin);
+ * }
+ * });
+ * </code></pre>
+ * Setting up the consumer:
+ * <pre><code>
+ * var socket = new easyXDM.Socket({
+ * remote: "http://remotedomain/page.html",
+ * remoteHelper: "http://remotedomain/name.html",
+ * onReady: function(){
+ * // you need to wait for the onReady callback before using the socket
+ * socket.postMessage("foo-message");
+ * },
+ * onMessage: function(message, origin) {
+ * alert("received " + message + " from " + origin);
+ * }
+ * });
+ * </code></pre>
+ * If you are unable to upload the <code>name.html</code> file to the consumers domain then remove the <code>remoteHelper</code> property

+ * @cfg {String/Window} local The url to the local name.html document, a local static file, or a reference to the local window.

+ * @cfg {String} remote (Consumer only) The url to the providers document.
+ * @cfg {String} remoteHelper (Consumer only) The url to the remote name.html file. This is to support NameTransport as a fallback. Optional.

+ * @cfg {Number} interval The interval used when polling for messages. Optional, defaults to 300.
+ * @cfg {String} channel (Consumer only) The name of the channel to use. Can be used to set consistent iframe names. Must be unique. Optional.
+ * @cfg {Function} onMessage The method that should handle incoming messages.<br/> This method should accept two arguments, the message as a string, and the origin as a string. Optional.
+ * @cfg {Function} onReady A method that should be called when the transport is ready. Optional.
+ * @cfg {DOMElement|String} container (Consumer only) The element, or the id of the element that the primary iframe should be inserted into. If not set then the iframe will be positioned off-screen. Optional.
+ * @cfg {Array/String} acl (Provider only) Here you can specify which '[protocol]://[domain]' patterns that should be allowed to act as the consumer towards this provider.<br/>
+ * This can contain the wildcards ? and *. Examples are 'http://example.com', '*.foo.com' and '*dom?.com'. If you want to use reqular expressions then you pattern needs to start with ^ and end with $.
+ * If none of the patterns match an Error will be thrown.
+ * @cfg {Object} props (Consumer only) Additional properties that should be applied to the iframe. This can also contain nested objects e.g: <code>{style:{width:"100px", height:"100px"}}</code>.

+/**
+ * @class easyXDM.Rpc
+ * Creates a proxy object that can be used to call methods implemented on the remote end of the channel, and also to provide the implementation
+ * of methods to be called from the remote end.<br/>
+ * The instantiated object will have methods matching those specified in <code>config.remote</code>.<br/>
+ * This requires the JSON object present in the document, either natively, using json.org's json2 or as a wrapper around library spesific methods.
+ * <h2>How to set up</h2>
+ * <pre><code>
+ * var rpc = new easyXDM.Rpc({
+ * // this configuration is equal to that used by the Socket.
+ * remote: "http://remotedomain/...",
+ * onReady: function(){
+ * // you need to wait for the onReady callback before using the proxy
+ * rpc.foo(...
+ * }
+ * },{
+ * local: {..},
+ * remote: {..}
+ * });
+ * </code></pre>
+ *
+ * <h2>Exposing functions (procedures)</h2>
+ * <pre><code>
+ * var rpc = new easyXDM.Rpc({
+ * ...
+ * },{
+ * local: {
+ * nameOfMethod: {
+ * method: function(arg1, arg2, success, error){
+ * ...
+ * }
+ * },
+ * // with shorthand notation
+ * nameOfAnotherMethod: function(arg1, arg2, success, error){
+ * }
+ * },
+ * remote: {...}
+ * });
+ * </code></pre>
+
+ * The function referenced by [method] will receive the passed arguments followed by the callback functions <code>success</code> and <code>error</code>.<br/>
+ * To send a successfull result back you can use
+ * <pre><code>
+ * return foo;
+ * </pre></code>
+ * or
+ * <pre><code>
+ * success(foo);
+ * </pre></code>
+ * To return an error you can use
+ * <pre><code>
+ * throw new Error("foo error");
+ * </code></pre>
+ * or
+ * <pre><code>
+ * error("foo error");
+ * </code></pre>
+ *
+ * <h2>Defining remotely exposed methods (procedures/notifications)</h2>
+ * The definition of the remote end is quite similar:
+ * <pre><code>
+ * var rpc = new easyXDM.Rpc({
+ * ...
+ * },{
+ * local: {...},
+ * remote: {
+ * nameOfMethod: {}
+ * }
+ * });
+ * </code></pre>
+ * To call a remote method use
+ * <pre><code>
+ * rpc.nameOfMethod("arg1", "arg2", function(value) {
+ * alert("success: " + value);
+ * }, function(message) {
+ * alert("error: " + message + );
+ * });
+ * </code></pre>
+ * Both the <code>success</code> and <code>errror</code> callbacks are optional.<br/>
+ * When called with no callback a JSON-RPC 2.0 notification will be executed.
+ * Be aware that you will not be notified of any errors with this method.
+ * <br/>
+ * <h2>Specifying a custom serializer</h2>
+ * If you do not want to use the JSON2 library for non-native JSON support, but instead capabilities provided by some other library
+ * then you can specify a custom serializer using <code>serializer: foo</code>
+ * <pre><code>
+ * var rpc = new easyXDM.Rpc({
+ * ...
+ * },{
+ * local: {...},
+ * remote: {...},
+ * serializer : {
+ * parse: function(string){ ... },
+ * stringify: function(object) {...}
+ * }
+ * });
+ * </code></pre>
+ * If <code>serializer</code> is set then the class will not attempt to use the native implementation.
+ * @namespace easyXDM
+ * @constructor
+ * @param {Object} config The underlying transports configuration. See easyXDM.Socket for available parameters.
+ * @param {Object} jsonRpcConfig The description of the interface to implement.
