To avoid a crash in TotalSigmaFunctionX I added a check that the histogram being fitted has
GetEffectiveEntries() > 10. This avoids a fit to no data, which will crash when you try to
get a fitted parameter. It could be that there is a mistake in the code leading to the
histogram being empty in the first place.
Removed superfluous print statement.
Tidy of pyEudetAnalysisOnly.py, but no changes of method.
Added comment on purpose of the file.
Removed commented out test code.
Simplified canvas saving.
Resized some canvases.
Didn't remove commented out code relating to calibration / landau fits.
We should add a proper example of how to calibrate somewhere.
Merge pull request #4 from sredford/master

Mainly a tidy of pyEudetAnalysisOnly.py, also catching a crash from TotalSigmaFunctionX
