* {boolean} [cleanSession] The server will persist state of the session if true. Not avaliable in beta.
* {boolean} [useSSL] The option to use SSL websockets. Default is false for now.
* {object} [invocationContext] An object to wrap all the important variables needed for the onFalure and onSuccess functions. The default is empty.
* {function} [onSuccess] A callback to operate on the result of a sucessful connect. In beta the default is just the invoking of the `callback` parameter with the data from the connection.
