/**
 * @class easyXDM.Socket
 * This class creates a transport channel between two domains that is usable for sending and receiving string-based messages.<br/>
 * The channel is reliable, supports queueing, and ensures that the message originates from the expected domain.<br/>
 * Internally different stacks will be used depending on the browsers features and the available parameters.
 * <h2>How to set up</h2>
 * Setting up the provider:
 * <pre><code>
 * var socket = new easyXDM.Socket({
 * &nbsp; local: "name.html",
 * &nbsp; onReady: function(){
 * &nbsp; &nbsp; &#47;&#47; you need to wait for the onReady callback before using the socket
 * &nbsp; &nbsp; socket.postMessage("foo-message");
 * &nbsp; },
 * &nbsp; onMessage: function(message, origin) {
 * &nbsp;&nbsp; alert("received " + message + " from " + origin);
 * &nbsp; }
 * });
 * </code></pre>
 * Setting up the consumer:
 * <pre><code>
 * var socket = new easyXDM.Socket({
 * &nbsp; remote: "http:&#47;&#47;remotedomain/page.html",
 * &nbsp; remoteHelper: "http:&#47;&#47;remotedomain/name.html",
 * &nbsp; onReady: function(){
 * &nbsp; &nbsp; &#47;&#47; you need to wait for the onReady callback before using the socket
 * &nbsp; &nbsp; socket.postMessage("foo-message");
 * &nbsp; },
 * &nbsp; onMessage: function(message, origin) {
 * &nbsp;&nbsp; alert("received " + message + " from " + origin);
 * &nbsp; }
 * });
 * </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
 * and easyXDM will fall back to using the HashTransport instead of the NameTransport when not able to use any of the primary transports.
 * @namespace easyXDM
 * @constructor
 * @cfg {String/Window} local The url to the local name.html document, a local static file, or a reference to the local window.
 * @cfg {Boolean} lazy (Consumer only) Set this to true if you want easyXDM to defer creating the transport until really needed.
 * @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} delay The number of milliseconds easyXDM should try to get a reference to the local window.  Optional, defaults to 2000.
 * @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>.
 * Properties such as 'name' and 'src' will be overrided. Optional.

 * &nbsp; local: {..},
 * &nbsp; remote: {..}
 * });
 * </code></pre>
 *
 * <h2>Exposing functions (procedures)</h2>
 * <pre><code>
 * var rpc = new easyXDM.Rpc({
 * &nbsp; ...
 * },{
 * &nbsp; local: {
 * &nbsp; &nbsp; nameOfMethod: {
 * &nbsp; &nbsp; &nbsp; method: function(arg1, arg2, success, error){
 * &nbsp; &nbsp; &nbsp; &nbsp; ...
 * &nbsp; &nbsp; &nbsp; }
 * &nbsp; &nbsp; },
 * &nbsp; &nbsp; &#47;&#47; with shorthand notation
 * &nbsp; &nbsp; nameOfAnotherMethod:  function(arg1, arg2, success, error){
 * &nbsp; &nbsp; }
 * &nbsp; },
 * &nbsp; 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({
 * &nbsp; ...
 * },{
 * &nbsp; local: {...},
 * &nbsp; remote: {
 * &nbsp; &nbsp; nameOfMethod: {}
 * &nbsp; }
 * });
 * </code></pre>
 * To call a remote method use
 * <pre><code>
 * rpc.nameOfMethod("arg1", "arg2", function(value) {
 * &nbsp; alert("success: " + value);
 * }, function(message) {
 * &nbsp; 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({
 * &nbsp; ...
 * },{
 * &nbsp; local: {...},
 * &nbsp; remote: {...},
 * &nbsp; serializer : {
 * &nbsp; &nbsp; parse: function(string){ ... },
 * &nbsp; &nbsp; stringify: function(object) {...}
 * &nbsp; }
 * });
 * </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.
