[dali-dev] Edit layer

[Paul Fullbright <paul.fullbright@xxxxxxxxxx>]

FYI,

I checked in a change to the fledgling "rewrite".  I also completely 
deleted the "edit" plugin.  After some cross-talk I had today with Ed 
Merks, I may have had an epiphany moment:  I don't think we need the 
edit plugin at all.

I think we can make use of EMF's edit *layer*, but I don't think we need 
to use the code that's generated for us.  I was able to get the 
properties view to update simply by creating a basic Adapter (the 
listener) and adding that to the object-in-question's eAdapters().  
Those adapters are notified whenever the model object changes anything.  
I also removed the EditingDomain object and replaced that with a 
BasicCommandStack, which is all we really need in order to update the 
object from the UI.

That leaves the outline view.  I'm working on that, but I think we can 
make do with a very simple tree and label provider.  Why we really need 
an "InheritanceItemProvider" I'm not sure.  Not sure at all.
