Detailed Description

-TDC
Utitlity for TDC calibration
 --- step 1: produce plots from MuFilterEff root file: makeCalibrationHistos(r,readHists=True,t0_channel=4)
                 histograms are in  /eos/experiment/sndlhc/calibration/commissioning/MuFilterEff_runXXX.root
 --- step 2: fill dictionary with calibration parameters per run: getCalibrationParameters(runList=options.runNumbers)
                 location of TDC plots/TCanvas /eos/experiment/sndlhc/calibration/commissioning/TDC
 --- getRunStatistics(r): returns number of fitted tracks for run r, useful to check if enough statistics
