Convert Matrix/EventWorkspace to MDWorkspace for viewing rectangular detectors

[Janik Zikovsky]

• Create a MD workspace for viewing in the SliceViewer/VATES with these dimensions:
  • X pixel coordinate
  • Y pixel coordinate
  • TOF/dSpacing/whatever the dimension of each spectrum is
  • Possibly a 4th dimension = bank/detector number
  • Maybe even a 5th dimension = run number
• Convert the events from spectrum ID/TOF to these coordinates
• Possibly, create a MDHistoWorkspace at the same time with the "natural" binning of these events (creating one MDBox per pixel per bin would be way too much memory)
• View in SliceViewer

Refs #4939: algorithm to view detector face as MD works pretty well

for single bank; viewing multiple banks works but not as well.

Refs #4939 added tests, using MDEvent instead of MDLeanEvent

Note to testers: currently only works with RectangularDetectors. You might need to rebin to a MDHisto for the view to be more reasonable (or use dynamic rebinning).

[Owen Arnold]

Works as expected for rectangular detectors.
