    This file creates a global JSON object containing two methods: stringify
    and parse.

        JSON.stringify(value, replacer, space)
            value       any JavaScript value, usually an object or array.

            replacer    an optional parameter that determines how object
                        values are stringified for objects. It can be a
                        function or an array of strings.

            space       an optional parameter that specifies the indentation
                        of nested structures. If it is omitted, the text will
                        be packed without extra whitespace. If it is a number,
                        it will specify the number of spaces to indent at each
                        level. If it is a string (such as '\t' or '&nbsp;'),
                        it contains the characters used to indent at each level.

            This method produces a JSON text from a JavaScript value.

            When an object value is found, if the object contains a toJSON
            method, its toJSON method will be called and the result will be
            stringified. A toJSON method does not serialize: it returns the
            value represented by the name/value pair that should be serialized,
            or undefined if nothing should be serialized. The toJSON method
            will be passed the key associated with the value, and this will be
            bound to the value

            For example, this would serialize Dates as ISO strings.

                Date.prototype.toJSON = function (key) {
                    function f(n) {
                        // Format integers to have at least two digits.
                        return n < 10 ? '0' + n : n;
                    }

                    return this.getUTCFullYear()   + '-' +
                         f(this.getUTCMonth() + 1) + '-' +
                         f(this.getUTCDate())      + 'T' +
                         f(this.getUTCHours())     + ':' +
                         f(this.getUTCMinutes())   + ':' +
                         f(this.getUTCSeconds())   + 'Z';
                };

            You can provide an optional replacer method. It will be passed the
            key and value of each member, with this bound to the containing
            object. The value that is returned from your method will be
            serialized. If your method returns undefined, then the member will
            be excluded from the serialization.

            If the replacer parameter is an array of strings, then it will be
            used to select the members to be serialized. It filters the results
            such that only members with keys listed in the replacer array are
            stringified.

            Values that do not have JSON representations, such as undefined or
            functions, will not be serialized. Such values in objects will be
            dropped; in arrays they will be replaced with null. You can use
            a replacer function to replace those with JSON values.
            JSON.stringify(undefined) returns undefined.

            The optional space parameter produces a stringification of the
            value that is filled with line breaks and indentation to make it
            easier to read.

            If the space parameter is a non-empty string, then that string will
            be used for indentation. If the space parameter is a number, then
            the indentation will be that many spaces.

            Example:

            text = JSON.stringify(['e', {pluribus: 'unum'}]);
            // text is '["e",{"pluribus":"unum"}]'


            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'

            text = JSON.stringify([new Date()], function (key, value) {
                return this[key] instanceof Date ?
                    'Date(' + this[key] + ')' : value;
            });
            // text is '["Date(---current time---)"]'


        JSON.parse(text, reviver)
            This method parses a JSON text to produce an object or array.
            It can throw a SyntaxError exception.

            The optional reviver parameter is a function that can filter and
            transform the results. It receives each of the keys and values,
            and its return value is used instead of the original value.
            If it returns what it received, then the structure is not modified.
            If it returns undefined then the member is deleted.

            Example:

            // Parse the text. Values that look like ISO date strings will
            // be converted to Date objects.

            myData = JSON.parse(text, function (key, value) {
                var a;
                if (typeof value === 'string') {
                    a =
/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
                    if (a) {
                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
                            +a[5], +a[6]));
                    }
                }
                return value;
            });

            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
                var d;
                if (typeof value === 'string' &&
                        value.slice(0, 5) === 'Date(' &&
                        value.slice(-1) === ')') {
                    d = new Date(value.slice(5, -1));
                    if (d) {

// We split the second stage into 4 regexp operations in order to work around

// replace the JSON backslash pairs with '@' (a non-JSON character). Second, we
// replace all simple value tokens with ']' characters. Third, we delete all
// open brackets that follow a colon or comma or that begin the text. Finally,
// we look to see that the remaining characters are only whitespace or ']' or

/**
 * @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.

/** 
 * @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({
 * &nbsp; &#47;&#47; this configuration is equal to that used by the Socket.
 * &nbsp; remote: "http:&#47;&#47;remotedomain/...",
 * &nbsp; onReady: function(){
 * &nbsp; &nbsp; &#47;&#47; you need to wait for the onReady callback before using the proxy
 * &nbsp; &nbsp; rpc.foo(...
 * &nbsp; }
 * },{
 * &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.
