MarkM and Ravi collect a lunch offer!

[Eric Dean Tribble <tribble>]

MarkM and Ravi get to collect my lunch offer for improvements to the
SpatialBehavior protocol.  I believe MarkM had the originating idea
that will actually end up eliminating the SpatialBehavior class (in
the next cycle of improvements to the Ent).  Ravi just finished fixing
the current Ent code so that it uses the distinction regions that form
the basis for the improvement.  Congratulations!
