Add documentation using Sphinx-apidoc and Read The Docs for automated docs

[sword134]

Hello,

I've stumbled upon this package and made a local clone on which I am sucessfully running sphinx for documentation purposes. The package already has extensive docstrings for each class and function.

It takes a few minutes to get the hang of and setup, but i'd say its well worth it and would allow for a new users to get involved with the package and potentially open pull requests in the future.
