[Rivet] Fuzzy bin filling in Rivet/YODA

[Andy Buckley]

Others way well have already realised this, but I think the histogram 
object indirection mechanism being added to Rivet for the 
NLO/multiweight branch will also allow us to neatly implement fuzzy bin 
filling without the analysis authors needing to do anything.

We could just override the fill() methods of the histo smart pointers, 
to decide whether to do normal or fuzzy fills based on the value of a 
new attribute on AnalysisHandler. I'm sure there will be minor technical 
impediments (e.g. the macroified way that the histo wrapping is 
currently done) but the principle seems neat. It could be an intrinsic 
part of Rivet "NLO mode".

This would be something to do *after* the current NLO/multi work -- 
there's quite enought to do there already. But nice to see that it 
aligns well with something else on our long-term to-do list :-)
