[Rivet] CMS_2011_S9120041, jet reconstruction

[Andy Buckley]

Hi Sercan,

Thanks for that. I've applied what I hope is a reasonable correction here:

https://rivet.hepforge.org/trac/changeset?reponame=&new=4079%40branches%2F2012-06-aidarivet%2Fsrc%2FAnalyses%2FCMS_2011_S9120041.cc&old=3921%40branches%2F2012-06-aidarivet%2Fsrc%2FAnalyses%2FCMS_2011_S9120041.cc

Can you check that this does what it should? I checked that it compiles,
and FourMomentum::isZero() should be safe.

Cheers :)
Andy
