Demo to Chris Mellish 2

Showed Chris the system working with ontology comparisons. He warned us to watch our choice of phrasings, for example giving a measure of information density is only as reliable as our ability to extract information from text.

Further work to be done to the system before performing evaluations:
Add the use of lexical and structural analysis to calculate measure statistics for use in comparisons
Add functionality for an overlap KB to be built from two KBs being compared: the overlap KB will contain all that is common to both original KBs.
Check the entire project for code worth cleaning.
Refine Learn GUI.
