* This class demonstrates some aspects of the OWL API. It expects three
* arguments:
*
* - The URI of an ontology
* - The URI of a reasoner
* - A location to place the results.
*
* When executed, the class will find all inconsistent classes in the ontology.
* For each inconsistent class, the debugger will be used to determine the set
* of support for the inconsistency. A report will then be written to the outpur
* file.
