Getting the cet bean utils so they use the most recent bean session APIS:

– Ensure that every mapping has a subject

– make sure that all access to mappings is by subject, not by rdf type since that is very fragile

– make sure that delegation is done

– make sure that duplicate code is not executed. e.g. checking beans for their subject properties right after a fetch. You cannot get a bean with a dud subject from the session.

– unit tests for basic functionality
