// THIS TEXT TO BE REPLACED BY ATLAS STANDARD FORMAT
//
//
// class: LArTTL1Overlay
//
// Description:
//
//The LArTTL1Overlay class takes calorimeter cells from the TES and
// forms Trigger Towers, which it then places back into the TES  The calorimeter
// cells can be produced either by GEANT or other fast simulation packages
// - this is defined by setting a parameter
// CellType to 1 for CaloCells, 2 to reprocess TriggerTowers and 3 for LAr/Tile TTL1 input (a simulation of analogue towers);
