Release 0.16.0

Summary: 0.16.0 introduced a number of refinements to the cellxgene application. We have added a number of UI enhancements such as histogram coloring, improvements to the differential expression user experience, and re-embeddings. This release also includes a large number of bug fixes and small performance improvements.

We are currently testing an alpha version of a hosted cellxgene at cellxgene.cziscience.com. While it is not yet feature complete, any feedback would be welcome.
