Title: Add links to Calvin papers

The Calvin papers are the source material for my talk, [PWL2#4](http://www.meetup.com/papers-we-love-too/events/171291972).

These papers are not licensed for inclusion in the git repo, so I added links to the README.

The five links are grouped under a single top-level bullet, because otherwise it would be hard to correlate them.
