2.0.1: initial alpha release

This is the initial alpha release of SourceTracker2, a Python 3 implementation of @danknights's SourceTracker developed by Biota Technology and released under the BSD 3-clause license.

This release implements the Gibb's sampler described in the original SourceTracker paper, and provides a command line interface through the sourcetracker2 command.

Installation instructions are provided in the project README.

Benefits over the original sourcetracker include parallel execution (call sourcetracker2 --jobs), and relaxed requirements on the sample metadata mapping file. We are next working on stabilizing the API, generating the plots provided by the R version of sourcetracker, and other features.

Please be aware that this is an alpha release, and as such you may find bugs. The command line interface should not yet be considered stable, but we'll do our best to minimize backward-incompatible changes. We're very interested in receving bug reports and feature requests, both of which can be submitted through our issue tracker.

Enjoy!
