Generate nix expressions for Python packages.

I needed something that can work not only with pypi but also with local paths, VCS links, and dependency links. I couldn't get any of the other generators to work, so I started my own :-)

$ git clone htts://github.com/ktosiek/pip2nix
$ nix-env -f pip2nix/release.nix -iA pip2nix.python34  # Same Python as target packages

To generate python-packages.nix for a set of requirements:

$ pip2nix generate -r requirements.txt

pip2nix generate takes the same set of package specifications pip install does.

Problems and questions should go to GitHub issues. If you need real-time help you can try pinging me - I'm ktosiek on Freenode, and @tkontusz on Twitter.
