Something just occurred to me:  I would guess that groups would be 
mostly manageable outside of the handle visualization.  The only place 
where I would envision a problem would be in the selection of objects in 
the visualizer (i.e. it would be logical to me that if the user selects 
an object in the visualizer the entire group associated with that object 
should be selected).  Off the top of my head other than that case, 
groups could be just made to exist within the structure of the handle.

I'm sure that I'm missing something (and please explain to me what I'm 
missing), but again, I really would like groups to exist.
