We're using [Sphinx](http://sphinx-doc.org/) and [sphinxcontrib-napoleon](https://pypi.python.org/pypi/sphinxcontrib-napoleon) to build documentation for parts of our project -- even though I don't think we're building docs for these files right now, it would still be good to get in the habit of having a consistent, parsable style for documenting things like function arguments. Can you document these arguments in one of the ways that these tools support? I'd be happy to help you out with that, if you'd like.
