Detailed Description

This produces a reco::MET object that stores MHT (or MET)

Author: Steven Lowette; Michele de Gruttola, Jia Fu Low (Nov 2013)

MHT (or MET) is calculated using one of the input collections:

Calo or PF jets
tracks
PF tracks
PF charged candidates
PF candidates MHT can include or exclude the contribution from muons.
