implementation of more complex electron systematics correlation models in Analysistop

Implementation in AnalysisTop of SIMPLIFIED and FULL correlation models for Isolation, ID and Reco systematics for electrons, as described in ANALYSISTO-809.

To use, add in config file: ElectronEfficiencySystematicModel SIMPLIFIED or ElectronEfficiencySystematicModel TOTAL

in output root file new branches with weights corresponding to the SIMPLIFIED/TOTAL model variations will appear. The old "TOTAL" variations are still present, in case analyses still want to use them for some components.

Et/eta bining customization, can be used e.g. with the following lines in the config file:

ElectronEfficiencySystematicModelEtaBinning 0.0:1.37:4.9 ElectronEfficiencySystematicModelEtBinning 4000:7000:10000:15000:20000:25000:30000:60000:80000:13000000
