Testing Instructions

• Check out this branch
• Run ./scripts/update
• Run ./scripts/server
• In another terminal window, query the run endpoint with the new example

  http --verbose :8090/run < examples/TR55_RasterGroupedCountMany.json

  • Ensure the output has multiple histograms, corresponding to the number and order of input polygons
