Q&A View must count and display the answers taking identical individuals and equivalent classes into account

[GoogleCodeExporter]

For example, the answer to the question "Who is a fireman?" should be:

Individuals (3): {Bill William}, Bob, John
Subclasses (0):
Superclasses (2): human, {man male}

where identical but differently named individuals should be grouped,
as should be sub/super classes which are equivalent.

To make this work for individuals make sure that the NodeSet policy
used by the reasoner is IndividualNodeSetPolicy.BY_SAME_AS
(note that the OWL-API default is BY_NAME).
