Working copy of pixython ... a python wrapper for the pixy camera library libpixyusb.
Notes:
    1 - Ony tested on Python 2.7 so far
    2 - Dependencies:
           pip install PyYAML
    3 - Need to be able to find shared library ... so before running python:
           LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
