v0.6.0

• Visualizations can now accept options, for example:
  • viewAsPairs and colorByInsert are options for pileup.viz.pileup
  • vafThreshold is an option to pileup.viz.coverage
• The new Location Omnibox combines start & stop values.
• You can enter full ranges like “chr17:1,234-2,345” into the omnibox directly (useful for copy/paste).
• Coverage Track now shows all bases (including the reference) for high VAF mismatches
• Added support for track option menus. The pileup track now exposes “View as Pairs” and “Color by Insert” in the UI.
• You can re-sort the pileup around the center base using the options menu. Sorting happens automatically on the initial load and after jumps.
• Eliminated Moiré patterns and improved crispness for all tracks.
• Fixed a bug where coverage values were inaccurate.
• pileup now uses off-screen buffers for faster rendering. After the initial drawing, panning should be extremely smooth.
• Performance optimizations to the 2bit data source (i.e. the reference)
• Internal: Updated all React components to be ES6 classes and added types for their props and state.
• Internal: Using travis-weigh-in to track code size
• Internal: Added screenshot tests (via seltest)
