Well, I just finished getting the last few bugs removed
from grouping 
and wrote the detector for the depends on
functionality.

I have 
had 12 node tree built to do the testing.

The only major problem 
was trying to keep the tree layouts
straight in my head. Then again it is 
5:37 AM here and
I have been working on this since yesterday 
AM.

The display is really the crux of this ticket. At this point 
I
think we have a proof of concept of detectors that
work.
