The ENVIMessageHandler class is an abstract class used as a superclass for other message handler classes.  Implementing this abstract class allows you to subscribe to the ENVIBroadcastChannel.
            ENVIBroadcastChannel will call the OnMessage method on all its subscribers to forward messages sent using the ENVIBroadcastChannel::Broadcast method.
