Cayenne will need to know this information. For instance, you might
have inheritance with an abstract superclass Person. Then performing
a query on that class, Cayenne will need to automatically return
objects of Student and Tutor subclasses and not the Person
superclass. Effectively the flag "setResolvingInherited" will be
switched on automatically.
If nothing else, this information needs to be stored in the Datamap
and the logical place is in the ObjEntity itself.
When we get to vertical inheritance there will be at least one other
property added to the ObjEntity: the name of the relationship used to
find the superclass.
