Title: Documenting the ptb module (and cousins, propbank_ptb and nombank_ptb)

Here is an attempt to document them in `test/corpus.doctest`. I realized that in order to share the necessary `allcats.txt` file there should be a dedicated `ptb3` package (always stored as a directory rather than a zip file so users can add/symlink the data directories). How should this be accomplished? I'm not familiar with the inner workings of the downloader tool.
