/**
* Given a set of ontologies, this composite change will convert all property
* assertion axioms whose subject is a 'punned' individual (i.e. an individual
* that shares a name with a class), removes these axioms and replaces them with
* annotations on the class that shares the same name as the individual. For
* example for a class A and an individual A, the data property assertion
* hasX(A, "Val") would be converted to an entity annotation on the class A with
* an annotation URI of "hasX" and a value of "Val".
* This composite change supports refactoring an ontology where punning was used
* to simulate annotations on a class rather than using actual annotations on a
* class.
