Docstrings and comments

[HilariusJeremy]

Hi, I saw the GitHub repo and it looks interesting. Do you mind if I submit a PR of function docstrings and instructive comments (citations, intuitive explanations, I/O dimension details, etc.)? I think this would be great since the goal of the project is educational and new people who jump in can do serious things faster!
