Detailed Description

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

Author: Steven Lowette; Michele de Gruttola, Jia Fu Low (Nov 2013); Thiago Tomei (added the "HT from CaloTower code")

HT & MHT are calculated using input CaloTower collection. HT is stored as sumet_, MHT is stored as p4_ in the output.

See header file for documentation
