Documentation

[yuzhiliu8]

currently we have unupdated READMEs spread out thru the monorepo and also some outdated slides in software drive, which is a hassle to maintain.

Should move all of our documentation to self hosted website on github pages.

Current choices:
MkDocs:

• Good support for Python, C++
• Autodoc API generation
• Uses markdowns to render, so integrates well with our current readmes

GitBook:

• No Autodoc generation
• more of a hassle to set up CI/CD
• Best looking themes

Sphinx:

• MkDocs but worse for our case.
