Add trijet analysis

Check out this branch of the code and compile custom branch of combine

cmsrel CMSSW_7_4_14
cd CMSSW_7_4_14/src
cmsenv
git clone -b trijet2016 https://github.com/CMSDIJET/DijetRootTreeAnalyzer CMSDIJET/DijetRootTreeAnalyzer 
git clone -b dijetpdf_74X https://github.com/RazorCMS/HiggsAnalysis-CombinedLimit HiggsAnalysis/CombinedLimit
cd HiggsAnalysis/CombinedLimit
scram b -j 4
cd $CMSSW_BASE/CMSDIJET/DijetRootTreeAnalyzer

Put full.root in inputs/ directory.

Run standalone fit and check GOF:

mkdir fits_2018_05_29
python python/BinnedFit.py -c config/dijet.config -l 35900  -b CaloTrijet2016 -d fits_2018_05_29 --fit-spectrum inputs/full.root

Grab signal shapes (from standard analysis... just a check):

wget https://github.com/CMSDIJET/DijetShapeInterpolator/raw/master/ResonanceShapes_qq_13TeV_CaloScouting_Spring16.root -P inputs/
wget https://github.com/CMSDIJET/DijetShapeInterpolator/raw/master/ResonanceShapes_qq_13TeV_CaloScouting_Spring16_JERUP.root -P inputs/
wget https://github.com/CMSDIJET/DijetShapeInterpolator/raw/master/ResonanceShapes_qq_13TeV_CaloScouting_Spring16_JERDOWN.root -P inputs/
wget https://github.com/CMSDIJET/DijetShapeInterpolator/raw/master/ResonanceShapes_qq_13TeV_CaloScouting_Spring16_JESUP.root -P inputs/
wget https://github.com/CMSDIJET/DijetShapeInterpolator/raw/master/ResonanceShapes_qq_13TeV_CaloScouting_Spring16_JESDOWN.root -P inputs/

Make (fake) datacards:

mkdir cards_qq_trijet
python python/WriteDataCard.py -m qq --mass 500 -i fits_2018_05_29/DijetFitResults_CaloTrijet2016.root -l 35900 -c config/dijet.config -b CaloTrijet2016 -d cards_qq_trijet/ inputs/ResonanceShapes_qq_13TeV_CaloScouting_Spring16.root inputs/full.root  --jesUp inputs/ResonanceShapes_qq_13TeV_CaloScouting_Spring16_JESUP.root --jesDown inputs/ResonanceShapes_qq_13TeV_CaloScouting_Spring16_JESDOWN.root --jerUp inputs/ResonanceShapes_qq_13TeV_CaloScouting_Spring16_JERUP.root --jerDown inputs/ResonanceShapes_qq_13TeV_CaloScouting_Spring16_JERDOWN.root --xsec 10

Run (fake) limits:

combine -M Asymptotic cards_qq_trijet/dijet_combine_qq_500_lumi-35.900_CaloTrijet2016.txt
