[Rivet] adding error bars, goodness of fit and sum defects

[Gavin Hesketh]

Hi Eike,
you might have to provide more specific information - eg which version 
of rivet, the full commend you use, the error message you get...

But you should also know that rivet does not treat correlations between 
uncertainties, so if you are looking at a systematics limited 
distribution the chi2 will not be fully correct.

cheers,
gavin
