Version 2.0.1

This is the official 2.0 release, plus a deployment fix! The 2.0.0 tag got deleted because it was only partially deployed due to an issue in the Dockerfile.

This release represents several months worth of work from a number of contributors, essentially rewriting most of the code base and hopefully making it more user-friendly and functional.
