Doxygen docs on readthedocs.org

[dfellis]

I'm making this an issue because I'm not sure if there's some other mechanism Uber plans to host documentation for OSS projects, but it seems reasonable to me for the h3 docs to be on readthedocs.org

Here's the official getting started page and here's a stackoverflow answer on how to integrate with doxygen

I will also note that readthedocs needs an account set up, so it probably would have to be someone at Uber to do this, but I can help review things if you decide to go with it.

We should definitely get a hosted copy of the built documentation. I'm also thinking about getting Github Pages setup. That doesn't have the same nice publishing tooling, but may be easier as we expand the documentation.

Docs are now live on https://uber.github.io/h3/ The source can be found in the website directory in the repo. Pull requests are of course welcome!

Awesome news! :)
