TOPAZ monitor position

[AndreiSavici]

The monitor before the sample should be at about -2.57m instead of -4.45. To test:

LoadNexusMonitors(Filename='TOPAZ_7892_event.nxs',OutputWorkspace='TM')
ConvertUnits(InputWorkspace='TM',OutputWorkspace='TMOrigK',Target='Momentum')
Rebin(InputWorkspace='TMOrigK',OutputWorkspace='TMOrigK',Params='0.2,0.01,5',PreserveEvents='0')

MoveInstrumentComponent(Workspace='TM',ComponentName='monitor1',Z='-2.57',RelativePosition='0')
ConvertUnits(InputWorkspace='TM',OutputWorkspace='TMNewK',Target='Momentum')
Rebin(InputWorkspace='TMNewK',OutputWorkspace='TMNewK',Params='0.2,0.01,5',PreserveEvents='0')

Load(Filename='TOPAZ_7892_event.nxs',OutputWorkspace='TOPAZ_7892_event')
ConvertUnits(InputWorkspace='TOPAZ_7892_event',OutputWorkspace='TOPAZ_7892_event',Target='Momentum')
Rebin(InputWorkspace='TOPAZ_7892_event',OutputWorkspace='TOPAZ_7892_event',Params='0.2,0.01,5',PreserveEvents='0')
SumSpectra(InputWorkspace='TOPAZ_7892_event',OutputWorkspace='sum')

Spectra for monitor 1,2, and the sum over all detectors should start at the same position in k (or lambda). Ignore the prompt pulse, that should be in different position.
