[Rivet] Quantify the "agreemnet" with Rivet

[Andy Buckley]

With Rivet 2 you also have full programmatic access to the histograms
via YODA, so it should not be a lot of work to make your own numerical
comparisons. The tools for doing this should improve as YODA and the
plotting tools develop and become better integrated. Contact us if you
need any help with using the YODA Python or C++ interfaces.

But the make-plots GoF measure suggested by Holger is definitely the
easiest "built-in" way at the moment, although it doesn't give you
_programmatic_ access to the quality of fit number.
