[Rivet] hepmc file name in analysis class?

[Kolja Kauder]

Hi Andy,

Understood, and I appreciate the concerns. Just to explain myself better,
the reason for wanting to do this because I use rivet as a hepmc processor,
i.e. I translate hepmc files into root trees. And in the current setup
there's no elegant way to customize an output filename from the input,
meaning I have to run individually and then cp or mv the result to the name
I actually want. That workflow does the trick, so my problems are "solved",
I just wanted to check for other options.

Fyi, when running over multiple files, my ideal interface would have been
something like handler().GetCurrentFile().GetName()

Thanks,
Kolja
