This member function sets lb as the lower bound of the invoking range, and it creates the appropriate instance of the undocumented class IChange to notify algorithms about this change of an extractable object in the model.

Accesses/sets the name assigned to the invoking modeling object. If the invoking modeling object has not been assigned a name, null is returned.
