Modified Files:
	pylib/TW/API [Simplification-Branch]: Advisors.py Interfaces.py
	    Interpreters.py Targets.py __init__.py

Log Message:
Tightened up the pre/postconditions of methods in the build process, so
that it's clearer what advisors and interpreters can and cannot do to
build targets at different points in time.  Added checks to make sure that
the rules can't be broken, and that reasonable error messages occur when
code tries to break them.  Also, did a little performance tuning, there's
now a lot fewer calls to most routines, especially since I inlined a couple
more common cases.  It should now be possible to enhance Bundles to allow
for auto-include of missing required bundles, "sideways inheritance" from
a bundle, etc.  The interface docs are still in progress, and Targets.py
still needs more cleaning, but at least some progress is being made.
