Adaptable Q-radius for spherical integration

Reported by: Peter Peterson Owned by: Vickie Lynch
Priority: major Milestone: Release 3.0
Component: Diffraction Keywords:
Cc: Blocked By:
Blocking: Tester: Peter Peterson

Description

Add an additional parameter to IntegratePeaksMD that would be used in place of PeakRadius. This additional parameter would be a constant for deltaQ/Q used to calculate the radius of the sphere so each peak has a different radius related to the magnitude of Q at its center such that 

PeakRadius_thispeak = (deltaQ/Q) * Qcenter_thispeak

I really wanted to pass this one, but there is a problem. If I set AdaptiveQRadius to True/False with the same PeakRadius the slice viewer shows the peaks to be the same size. The intensities do differ so I believe this is just a mistake in what the radius is marked as in the individual peak.
