0.3.11 - Metadata Versioning and Better Docs

This is an exciting new release for us and includes a feature we've been working on for a couple months now: Metadata Versioning!
Check out ds.as_of() and ds.select() to start querying and comparing older data.

Along with versioning we improved our docs infrastructure and moved it to Sphinx. You can find the documentation here
