[kepler-dev] handling layer events

I'm trying to enable the canvas to allow a user to drag an actor from  
the canvas back to the actor library.  I've got the drag n' drop  
working, except that I can't seem to figure out how to get a  
reference to the NamedObj that implements the diva Figure on the  
canvas.  I have a reference to the Figure and also a reference to the  
root model itself, but how do I get a reference to the NamedObj that  
the Figure represents?  I'm working within the confines of  
BasicGraphFrame and the LayerAdapter that is implemented there.  My  
question is, how do I reconcile a Figure with a NamedObj so that when  
I drop the actor (or director or whatever) onto the actor library, i  
can process the actual ptolemy object instead of the diva object?
