//Program to read data from root file and make invarient mass hist
// Based on: https://mhance.scipp.ucsc.edu/analysisintro.php
//V2: Taken from HEP_practice program, then fitted for CERN data. Got Invarient mass for Z with muons
//V3: Added invarient mass for W with electrons using transverse mass
//V4: Changes made with Nick, added Iso bounds and UseAllMuonsForW bool to get only pos muons for W+. Adding more hists for mT and MET
//V5: Fixing MET_phi
//V6: Added more iso hists
//V7: Adding electron W's back.
///Note: Add WElectrons to WMuons or keep them seperate (currently seperate)
//V8: Added bJet with Nick, not working correctly? Keeps crashing when added bJet with WMuon
//V9: Fixed V8 so it will run
//V10: Made NMuon and NJet = 2 case allowed. This is not the whole picture - Muons and Jets are not parallel arrays. Look in notebook to make V11
//V11:
//V12: Changes from 11/10
//V13: Huge overhall of WMuon and Top loop. They are now split into two loops
//V14: Changes made at the end of 11/12 class for data overlay. Now adding more to our data.
//V15: Changes made with Nick 11/15: Fixed NIsoMuon counter, needed to be at top of loop. Also fixed bug with "N_IsoMuon == 1;" not being "NIsoMuon == 1;"
//Notes from 11/15: Used NMuonIso instead of N_MuonIso and moved counter
//V16_TEMP: Changes being made to create Zs as done in the solution code. Attempt at seperating top - antitop onto seperate distributions. TEMP: Changes made during 11/17 class not present here (Should only have been some 2D IsoVPt hists)
//V16: Temp but with changes made during class 11/17.
//V17: Added 2D histogram of invariant mass of W vs invariant mass of top
///IT WORKS!!!!!
