fillTreeGen()

void MuScleFitPlotter::fillTreeGen

(

const std::vector< std::pair< reco::Particle::LorentzVector, reco::Particle::LorentzVector > > &

genPairs

)

Used when running on the root tree and there is genInfo.
ATTENTION: since we do not have any id information when reading from the root tree, we always fill the Z histograms by default.
