Log:
Preliminary istype() support for predicate dispatch.
This is just the necessary compiler support for translating expressions
of the form ``type(x) is y`` and ``x in istype(y)``, some support for
istype() implication/intersection with Class criteria, and a bit of 
cleanup/refactoring of the indexing code.

NOT supported: mixing istype() and Classes...  or actually indexing 
istype() criteria.  The entire BitmapIndex system is going to have to be 
refactored in order to fully fix this.  :(  On the bright side, that 
will let me clean up a bunch of other index-related cruft, too.
