Bad alloc when trying to open instrument view

[Owen Arnold]

It's absolutely essential to recover this functionality.

Workspace is at
olympic\BABYLON5\Public\Owen Arnold\problem_workspace. When trying to open the instrument view, I get a bad alloc unexpected exception.

[Russell Taylor]

Here's another way to get this problem (from Janik)....

Run this script:

LoadEventNexus(Filename=r'CNCS_7860_event.nxs',OutputWorkspace='cncs')
ConvertToMatrixWorkspace(InputWorkspace='cncs',OutputWorkspace='a')
Power('a', 'am1', -1)

Right-click on am1 workspace, select instrument view. You will get at bad_alloc error. I think it is related to the fact that there are "inf" values in the Y data.

Following Russell/Janik's suggestion, I ran ReplaceSpecialValues algorithm prior to running the instrument view. After doing this, I was able to view the workspace in the instrument view. Roman, should try this out too.

If this is the cause of the problem, we would still need to fix the bad_alloc error and gracefully suggest to the user the course of action to follow to correct for special values.

Re #4079. Added some protection against infinites and NaNs

Bad alloc no longer occurs when the script above is used - the user is now prompted to run ReplaceSpecialValues instead.
