IDA Absorption Corrections tab

[DanNixon]

Fixes #10903.

To test:

• Review documentation
• Open Indirect Data Analysis > Absorption Corrections
• Try a couple of calculations for each geometry (usage examples for algorithms have suitable sample/can dimensions)

Sample is: irs26176_graphite002_red.nxs
Can is: irs26173_graphite002_red.nxs

All looks good to me. The documentation is clear and goes to the point. I'd perfectly know how to use this interface even though I have no clue of the theory and calculations behind. I tried the 3 geometries and it seems to be lousy-user-proof. Strange values (0, etc.) are handled with informative errrors.

Maybe the only detail that was not obvious/explicit to me at first is that when you enable 'Save Result' the files are named exactly as the workspaces, simply appending .nxs, like irs26176_graphite002_FlatPlate_Corrected.nxs. There could be a note about this in the description of "Save Result", but that can always be added later.
