Supported version of Python not specified

There is no indication regarding Python 2/3 support. Could be included in setup.py and/or README.

Hey Antoine. Our code was tested on 2.x but we haven't explicitly tested it with 3.x to see if it's compatible. I'll take a look at it soon and make setup.py enforce/specify the Python version.
