The plot produced by the Step Scan Interface needs to include errors

[Russell Taylor]

This is easy if just plotting Counts (just add a column to the table with sqrt(events) ), but will be a bit more work if any normalising is done.

Re #7767. Tweak the performance test.

To see if it leads to 'steadier' performance.

Re #7767. Add boilerplate test initialisation code.

Nothing to do with this ticket, but realised I missed this when I added this performance test recently.

Re #7767. Change title of workspace corresponding to plot.

People are going to want to fit to this data, so it doesn't make sense to make it a hidden workspace. Also amended the name so it starts with the same string as the table workspace.

Tester: Branch is feature/7767_stepscan_add_errors

Despite the description, this was also easy for the normalisation case as I'm using the binary operations, which just do it right. So all that was required was to add the new error column when calling ConvertTableToMatrixWorkspace the first time in the StepScan custom interface.

To test, start up the Step Scan Interface from the Interfaces menu. The reference data to load is HYSA_2934.nxs.h5 from the systemtests repository. Just hit start once the file is loaded and you will see (very small) errors on the plot. Try changing the normalisation and check the errors update correctly. Note that the errors in this case will be wrong if #7779 hasn't already been merged - this is particularly noticeable if normalising by time. You can bring up the table and confirm that the error column correctly holds sqrt(counts).
