/// <summary>This file contains common code that assists in hooking up CSMF communications in a way that
///          allows an initialization method to be called when the communications have been established
///          and it is ready to start receiving requests
///</summary>
///<remarks>
///     This code hooks up to the CSMF's widget onmessage method to handle communications coming back
/// from the widgetServer (remote server).  Based on the widget that's communicating it will a. call
///  a readyInitialize function that's been defined for that specific widget once communications have
///  been established.  b. all subsequent messages for that specific widget will be forwarded to the
///  specific widget's onmessage handler.
///  In order to use this infrastructure, each widget will need to create an object that contains the
///  methods readyInitialize, and onmessage, and store a reference to them in the jQuery data storage
///  keyed by the name of the widget.
/// </remarks>
