Lighter weight interactive classification tool

[karlcz]

There is recurring interest in a lighter weight classification tool to use instead of synspy-viewer which depends on doing OpenCL and OpenGL with high performance processors and large working RAM. Instead, users want it to fit in a typical laptop's hardware specs and slower wide-area networks.

Possible concessions to reduce the footprint:

• Refactor the image processing to be done ahead of time on the server and provide downloadable assets for this new tool
  • An image stack optimized for download, e.g. compressed and possibly decomposed into several files
  • The centroid CSV dump we already generate
• Take advantage of the region of interest slicing to reduce working space
  • Smaller image
  • Smaller centroid lists
• Support only XY slicer instead of volumetric rendering
  • No off-axis slicing so only one slice needs to be loaded and rendered at a time
  • No need for large 3D texture that exhausts available GPU RAM
• Possibly down-sample the image grid spacing if full resolution isn't needed?

Besides the hardware footprint, another issue is the delivering the software stack into a less well managed laptop environment. Being able to drop the main OpenCL analysis would avoid some complex library and driver issues.

• [x] synspy-analyze for non-interactive pre-processing
• [x] synspy-viewer2d for interactive classification
• [x] add t/T controls to adjust black level
• [x] catalog schema updates to track ROI NPZ file
• [x] server-side automation to run synspy-analyze on new images
• [x] synspy-launcher adjustments to run synspy-viewer2d instead of synspy-viewer (3d)
• bundled version of synspy-launcher and synspy-viewer2d as single program
  • [x] for windows
  • [x] for mac os x

This is mostly feature complete now as synspy-analyze and synspy-viewer2d. Needs some user acceptance testing and packaging/bundling validation next.

Users want to keep the "t/T" key controls from the 3d viewer. This was a control that evolved over time into a bit of a misnomer... it controlled the fully transparent zero point (where transparency was proportional to signal) and best corresponds to black level in the 2d slicer.

The production server has been upgraded and is now compatible with this new client tool, so we should build the production client once the bundling kinks are worked out... @mikedarcy

The production server was updated in concert with the latest launcher changes again. Bill is testing the revised launcher and viewers. Assuming he doesn't find blocker problems, we should get a bundle of the current release out with the 2d viewer and launcher combo.

Considering this released at v20170713.6 and pre-built launcher bundles will follow...
