ExtractMaskToTable bug

[peterfpeterson]

This hasn't been fully characterized yet, but Antonio said:

I was under the impression that the mask bins from table was running however if the 
same bin is masked on two non-intercepting ranges, clearly something does not work 
properly as we still have some remaining unmasked bins, furthermore I have been 
faced with repeated segmentation faults (see error below).

Would it be possible to discuss this capability, and what it is used for, with the 
person responsible so that we can sort this out for good?

Thanks

Antonio

To reproduce the bug (data file doesn't matter):

1. LoadEventNexus(SNAP_14666_event.nxs)
2. Bring up the instrument view and rotate to see a single side of the instrument and switch to the Mask/Group tab
3. Reduce the TOF range to 1000-2000 (arbitrary)
4. Mask a region and "Apply and Save" "As Mask to table"
5. Close the instrument view
6. MaskBinsFromTable with that workspace
7. Bring up the instrument view again
8. Change the TOF range to 1500-2500 (arbitrary but partially overlapping)
9. Mask an overlapping region and "Apply and Save" "As Mask to table"
10. CRASH!
