    Description

      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.
