/**
* A delegator forwards messages to a delegate object.
* Delegators are used when you need to multiplex messages
* toward any number of target objects.  
* For example, many controls may be connected to FXDelegator,
* instead of directly to the document object.  Changing the
* delegate in FXDelegator will then reconnect the controls with their
* new target.
