Documentation

Uses dgeni, the wonderful documentation generator built by @petebacondarwin.

To view docs:

1. gulp docs, which builds the docs to dist/docs
2. cd dist/docs and start an http server (e.g. python -m SimpleHTTPServer)
3. Navigate to the server, and enjoy (e.g. http://localhost:8000)

Run gulp watch to watch and rebuild docs on every save.
