Detailed Description

Description: edmFilter to select a TTBar decay channel

Implementation: decayType: 1 + leptonFlavour: 0 -> Semi-leptonic leptonFlavour: 1 -> Semi-e leptonFlavour: 2 -> Semi-mu leptonFlavour: 3 -> Semi-tau decayType: 2 -> di-leptonic (no seperate channels implemented yet)

decayType: 3 -> fully-hadronic
