Add support for reconstruction of "turbine" endcap ecal (#88)
* Add support for endcap turbine calorimeter * Add support for endcap turbine calorimeter * Add support for endcap turbine calorimeter * Added endcap turbine positioning tool * Minor changes (i.e. adding comments, removing commented lines * Remove segmentation members * Move most of the code in towersNumber to initialize * removal of bool member variables and change to interface of retrievePhiThetaExtrema * removal of bool member variables and change to interface of retrievePhiThetaExtrema * Changes to support turbine endcal ecal * Resolve conflicts * Change GaudiTool to AlgTool * Remove conflict text * update test scripts * remove EventCounter in tests (#105) Fix conflicts with main branch * Remove segmentation members Fix conflicts with main branch * Changes to support turbine endcal ecal Fix conflicts with main branch * update test scripts Fix conflicts with main branch --------- Co-authored-by: Erich Varnes <[email protected]> Co-authored-by: Giovanni Marchiori <[email protected]>
