0005  *
0006  *  \brief  This produces a reco::MET object that stores MHT (or MET)
0007  *  \author Steven Lowette
0008  *  \author Michele de Gruttola, Jia Fu Low (Nov 2013)
0009  *
0010  *  MHT (or MET) is calculated using one of the input collections:
0011  *    - Calo or PF jets
0012  *    - tracks
0013  *    - PF tracks
0014  *    - PF charged candidates
0015  *    - PF candidates
0016  *  MHT can include or exclude the contribution from muons.
