IntegratePeaksMD: determine when the peak radius or background shell is falling off the detector edge

[mantid-builder]

Original Reporter: @jzikovsky

Possibility one:

• Like the inelastic people, create events for every bin so we know our coverage.
  • This is the OneEventPerBin option of ConvertToDiffractionMDWorkspace
  • Perhaps set the edge pixels to NANs to be a clear flag that you are going over the edge?

Possibility two:

• It might be fastest to back-calculate the detector pixel and some points along the EDGES of the integration radii. Check if these are off the detector or on a masked pixel (requires the original MatrixWorkspace!). Flag radiuses that are too large?
  • Look at Peak::findDetector() method for the ray-tracing code that finds a detector.
  • The PredictPeaks::doHKL() builds up the Q vector to search for.
