Log Message:
Added '_onLink()' and '_onUnlink()' hooks for validation, etc.  Added
support for Immutable objects to be initialized via keyword arguments, with
rudimentary support for optional use of slots in place of a dictionary.
This will need to get ripped out and replaced with decent slot support in
the structural feature itself, I think.  Also added some (very) rudimentary
testing of immutable objects.
