FR 898

FR Number	Problem Description
898	Adding function to actor abstract class causes delta to show up in subclass.
Full Description A hollow delta indicates that the local version of an object (actor, protocol, etc) is the same as that stored in the library. When the local version is changed the delta changes to solid, indicating that the object should be checked back into the library. ObjecTime Developer ensures that the delta will be updated whenever an applicable change occurs, however, the current implementation is overly safe in that the delta is sometimes updated even when the change is not really applicable. For example, a subclasses' delta is updated when a superclasses' behaviour changes.
