e-mu CR

This is the current state of the emu-CR, i.e.:

• in the MET proxy the muon is treated as invisible and the electron pT is scaled by 1.1
• The Higgs candidate is reconstructed using the electron and the leading b-jet
• treats the electron as the leading b-jet

note that the electron also increases the N_Bjet. Open for ideas on how to make my code in XAMPPmonoH/Root/MonoHMetSelector.cxx less ugly. @jburr @changqia
