Documentation updates

Summary:Added some missing documentation.

I didn't really document `RichUtils`, I just added a placeholder so it's at least easy to find out which methods are available without having to resort to the source code (and the names should be self explanatory enough for it to be good for now).

Resolves #263
Closes #269
