SANS: SaveRKH does not save correct the SpectrumNumber

[Gesner Passos]

Execute the following script and although you would expect that the resulting file would have the spectrum index as 100, 101, the end result is 1,2

datax = [1,2,3,4,5]
datay = [2,3,4,5]
datae=[0.4,0.5,0,0]
ws = CreateWorkspace(datax,datay,datae,NSpec=1)
ws = Transpose(ws)
offset = 100
for i in range(ws.getNumberHistograms()):
	ws.getSpectrum(i).setSpectrumNo(i+offset)
print ws.getSpectrum(0).getSpectrumNo()
SaveRKH(ws,'/tmp/test.dat', Append=False)

Correct this.

This one currently is correct, and should continue to work

#for loq
ws = LoadRaw('99631')
ws = Integration(ws)
ws = CropWorkspace(ws,StartWorkspaceIndex=100,EndWorkspaceIndex=200)
SaveRKH(ws,'/tmp/test.dat', Append=False)

Tester:

run both scripts and make sure that the output file ('tmp/test.dat') has the spectrum index starting around 100. (Just open the file in a normal editor, and check that the first column starts with 100 or 101)

The non-working example given here is in a sense invalid as in that case you don't end up with a SpectraAxis up the side of the workspace, whereas with an actual SANS reduction I think you would. Possibly SaveRKH should check for that when it tests the dimensions of the workspace.

Still, in the case where you definitely want a spectrum number, I do encourage going via ISpectrum::getSpectrum rather than via the axis.
