setup.py should not attempt to install argparse on python >= 2.7

[gholms]

The argparse module is part of the python standard library beginning with python 2.7. When run on a system with that version, setup.py still wants to download and install argparse despite that. The install_requires list should probably be defined in an if statement earlier in the file to prevent that from happening.

I'm looking to correct this using environment markers such as below. This works on 2.7 (in a virtualenv) but I see it still installs argparse due to another package requiring it apparently. (it installs argparse 1.3.0 whereas below I ask for 1.2.2).
