Hi (cc @mhodgkin @cdelitzs @lmiller )
Implemented the TrackCaloCluster links to Electrons/Photons/Muons in PFCfg.py as an extension of the "new style" configuration of Flow Elements. In short, this means the linker algorithm can be run either in the "new style" PF configuration (RawToESD) or in the derivation framework using AOD input on TrackCaloClusters with no CPP changes at all (besides a nullptr catch added to the linker algorithm, and renaming of linker containers in the AOD run).
Implemented the configuration of the Flow Element links to Electrons/Photons/Muons in the "new-style" prototype configuration - PFRun3Config.py. After a discussion with @mhodgkin, this is NOT the production configuration needed for reprocessing.
