* This class demonstrates some aspects of the OWL API. It expects three

* arguments:

* <ol>

* <li>The URI of an ontology</li>

* <li>The URI of destination</li>

* <li>The URI of a class</li>

* </ol>

* 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.
