Transform .md files into documentation

[nathanshammah]

It could be nice to transform the full guide from .md files into a documentation, thus generating a website such as the ones hosted on Read the Docs.

• One way to go is to transform them into .rst files.
• The other way is to use some markdown to rst converter, such as m2r or similar to do the job, keeping all the docs in md, but reorganizing them.

Example

The cirq documentation is in md files.
