/**
 * This class demonstrates some aspects of the OWL API. It expects three
 * arguments:
 * 
 * The URI of an ontology
 * The URI of destination
 * The URI of a class
 * 
 * When executed, the class will find all subclass axioms that form part of the
 * definition of the given class. For each of these, if the superclass is a
 * conjunction of existential restrictions, then an additional subclass axiom
 * will be added to the ontology, "closing" the restrictions.
