Rick Altherr c815d4b1a5 Set tool and script paths project-wide 
utils/environment.sh determines its absolute path and then creates
environment variables to each of the prjxray tools.  This allows moving
the tools around in the code base without touching every script.

Purpose:
Try to show there are LUT enable bits ("buffer enable")

Algorithm:
Generate a design with a bunch of randomly initialized LUT6s
Generate a list of fully used LUT6s and fully unused LUT6s
Compare the lists to look for enable bits

Outcome:
Did not see existance of such bits
