Log Message:
Added QueryLink proxy class for computed associations.  Changed XMI DM
to use (read-only) PersistentQuery instances instead of PersistentList
objects, because such models are read-only right now anyway, and it
exercises PersistentQuery.  Of course, the load() method should probably
wrap them in QueryLinks, at least before we have write capability.
Refactored QueryLink and PersistentQuery to be based on the new
peak.util.ListProxy class, which implements common behavior for things that
want to act like lists, but delegate to a 'data' member that's the real
list, and return real lists from manipulation operations.
