[Rivet] stacking or adding .aida files

[Andy Buckley]

Or, since that is rather a lot of manual effort, use aida2root to 
convert our outputs to ROOT TGraphAsymmErrors objects which you can then 
do ROOTy things with. I'm not sure if that is easier, but it's an 
alternative and perhaps more familiar route!
