[Suggestion] Add documentation to the project

[BennetLeff]

Nanogui seems like a great GUI library for cross platform development. Unfortunately the lack of documentation creates a barrier to entry to developers such as myself. I would love to avoid using a monolithic GUI library like Qt. What can we do to add some documentation? I realize there's already an open suggestion to add instructions to using this library in other code but I think this suggestion would address even more future issues.

I'm open to other people contributing documentation but sadly don't have the resources to work on this myself. There is already another open ticket regarding docs, so I'm closing this one.

Fair enough, if I'm able to get going further with the project I'll try adding some documentation.

Thanks to the efforts of Stephen McDowell (@svenevs), we now have documentation!
