Allow hybrids across Model subclasses

Browse source 
A node could already implement a toDataElements() function that
returns a data element of another node type, but it couldn't return
an annotation or a meta item. This is fixed now, and any dm.Model
subclass can now morph into any other dm.Model subclass.

I didn't originally plan to do this today at all, but doing this now
makes my upcoming converter changes easier. Surprise feature!
