MMA 13a works with python 2 or 3

[bvdp]

I have just uploaded mma-13a, a test version which supports Python 2.5+ and 3.x.

The calling script, mma.py, has a first line:

     #!/usr/bin/env python

To force the use of python 3.x you can do several things:

   1. Call the program using the command line "python3 mma.py"
   2. Change the first line from "python" to "python3"
   3. Check the file "python" on your computer. In most cases it is a sym-link to
       either /usr/bin/python2 or /usr/bin/python3. Modify as necessary

This version of mma has a few conditional switches to use 3 or 2 code (and a few is actually 2).

Would you guys and gals please bang on this and see what I've missed.
