chanzuckerberg/cellxgene: Release 0.13.0

Summary: 0.13.0 introduces a layout change, moving all continuous data histograms into a dedicated panel: the "right side bar". In addition, 0.13.0 includes significant improvements and bug fixes to the experimental "user annotation" feature.

Added:

• Introduced a "right side bar" containing all continuous metadata and gene expression histograms.
• [Experimental feature, may be incomplete or unstable] Significant improvements to the user annotation functionality, allowing users to annotate groups of cells with categorical metadata:
  • Command line options related to annotation renamed and reorganized -- see cellxgene launch --help for usage.
  • Added simple multi-user support for hosted instances of cellxgene, to avoid the possibility of users over-writing each others' metadata.
  • Add a provenance header to the annotations output CSV file.
  • Many bug fixes, usability and stability improvements.

Changed:

• Command line option --skip-qc/--run-qc (a toggle) changed to a flag named --skip-qc.
• Command line help (via the --help option) improved.
• Reorganized and improved cellxgene documentation, available at https://chanzuckerberg.github.io/cellxgene/.
• Javascript and Python package dependencies updated.
