Modified the test code to automatically pick up new tests. Just add your test file to

tests/__init__.py.  Fixed a bug in ZigZagLayout.  Added the BehaviorQuerySystem to allow querying
on behaviors.  Added the "ModulateColor" behavior which will continually shift a color along the HSV
plane.  Added TestBQS to test the behavior query system.  Modified Behavior to have a getLastOutput
and setLastOutput method.
