Work on Argparse

[mscook]

Argparse code was from Nabil's template. The template needs some work.

See:

• http://docs.python.org/2/howto/argparse.html
• http://docs.python.org/2/library/argparse.html#module-argparse

Specifically, look at setting the namespace to remove the global variable and also positional arguments (currently all appear to be optional).

This is mainly done in the v 0.2 release to be pushed today.
