WIP: Add code for POWHEG Higgs decay
In POWHEG-BOX generator, the default setting is turn off the Higgs decays. Therefore, for the ggH->H->ZZ decay, we have to turn on the decay use PYTHIA settings, as force H decay into ZZ, and ZZ decay into four leptons, which need a little modification on Gen/LbPowheg/src/component/PowhegProduction.cpp.
