Generate inline documentation

[Arian-D]

Use sphinx to get inline documentation.

Sphinx can now generate documentation from README.md and TODO.md. From e2d7b2a it can also generate inline code, but some of the stuff need to be explicit, and Bishoy's winrt calls might need to be documented.
clippy-server.pdf. is a demo of what it looks like, and it needs to be done better.

@alicebalayan will most likely have to see how to structure this and add a better theme.

There is a package to add type hints to the docs. I'll have to add that too
