/**
* For a given class, this composite change makes its told primitive subclasses
* mutually disjoint. For example, if B, C, and D are primitive subclasses of A
* then this composite change will make B, C, and D mutually disjoint.
* More formally, for a given class, A, and a set of ontologies, S, this method
* will obtain a set of classes, G, where all classes in G are named and
* primitive. Moreover, for any class, B in G, some ontology O in S will contain
* an axiom, SubClassOf(B, A). All classes in G will be made mutually disjoint
* by creating axiom(s) in a target ontology T.
* This composite change supports a common design pattern where primitive
* subclasses of a class are made mutually disjoint.
