> Implement horizontal inheritance. This requires:
> 1. Allow dbEntityName attribute to be null in <obj-entity ...>
> 2. Modeler changes to allow this to be set. Validation should require that
> any class set in this way should have at least one subclass.
> 3. Changes, particularly to SelectQuery, which accomodates this change and
> returns the appropriate objEntities.
