Make Package and Refactor

[Mchristos]

This repository is now easily installable as a package. I also refactored some names to make the import statements make a bit more sense.

• empowerment function in __init__.py for a more sensible import statement
• rename empowerment -> compute_empowerment
• rename module info_theory -> information_theory
• update README

Great that you make a package. requirements.txt instead of requirements.py? also, why not put install_requires install_requires =[ 'numpy', ] ... instead of requirements.py in the setup.py?

You're right, thanks for spotting. Will add an install_requires field and then remove requirements.py (should have been .txt you're right)

Thanks @tessavdheiden, I added the requirements to the setup.py

Sorry @tessavdheiden , need you to re-approve after making those changes
