Detailed Description

This produces a reco::MET object that stores HT and MHT.

Author

Steven Lowette

Michele de Gruttola, Jia Fu Low (Nov 2013)

HT & MHT are calculated using input CaloJet or PFJet collection. MHT can include or exclude the contribution from muons. HT is stored as sumet_, MHT is stored as p4_ in the output.
