trick/trick_source/trick_swig/swig_ref.cpp
Alex Lin 4ab584ed55 Support using Python 3 
Fixed the configure script to allow the user to specify using a python3
interpreter.  Had to change the the way to load the swig generated python modules.
Also had to change code dealing with python strings, oct, long, and
boolean operations.
