Basic support for exception verification in tests

Browse Source 
This probably needs to be expanded upon.  The basic functionality
added is to permit a test expectation clause to be a function which
takes some kind of exception type.  That function can then
perform any arbitrary checks and analyses it needs to confirm that
the exception which was caught passes muster for that test case.
