[Rivet] hepmc file name in analysis class?

[Kolja Kauder]

Hi Deepak,

If I understand correctly, that allows me to set the .yoda name, but
not the name of any custom output files. If I could intercept that
name from inside the framework, I can use a regex to create my own
name based on that; is that possible?

Thanks,
Kolja
