Detailed Description

Tools for handling HGCal trigger det-ID: in the current version of trhe HGCAL simulation only HGCalDetId for the TriggerCells (TC) are used and not HcalDetId as in the offline! As a consequence the class assumes that only DetIds of the first kind are used in the getTC* methods NOTE: this uses the trigger geometry hence would give wrong results when used for offline reco!!!!
