autopep8

Format the code according to pep8 using autopep8. 

'find . -name '*.py' | xargs autopep8 -i'

Not sure if you want to do this in a single commit (or at all). This really messes with the git history and makes using
git blame (and other git commands) really annoying but the code base is small and is probably going to change a lot in the coming months therefore the git history is going to 'recover' fast.
