// EMECConstruction
 
// Revision history:
 
//  LArEMECConstruction:
// 09-May-2001 WGS: Copied from Andrei Soukharev's EMECDetectorConstruction.
// 09-May-2001 WGS: Put in the LAr parent volumes for the endcaps.
// 09-Jan-2002 WGS: The LAr parent volume now comes from the calling routine.
//                  Any shifts in z are handled in the parent volume.
// 02-Dec-2002 J.Toth: wheels' shape and position are corrected;
//                   : support rings in front of sens.volume are introduced,
//                             like in endegeo.age of dice
// 13-Dec-2002 J.Toth: electrode shape is corrected
// 08-Jan-2003 J.Toth: the 11mm section between GTenbars and FrontFace
//                      of WheelSolid is added
//                     new 'average' materials G10FeInner, G10FeOuter are added
//                      for barrettes connecting long.bars and absorbers
// 24-Jan-2003 J.Toth: Code for Emec nonsensitive pieces is revised.
//                     details of emec support structure are added
//                       parameters for radial position of the rings
//                        are still in warm, while those for z positions are
//                        in cold.
//                     missing pieces:guides,feets
//                     Alu cone at Inner surface of Inner wheel is present
//                     new material PermaliE730 for FrontMiddleRing is added
//                       (composition to be checked)
//                     density of glue changed for that of prepreg glue of
//                       absorbers
 
// 21-Sep-2003        Revised to create EMEC mother volume, and to
// place all EMEC components (wheels,mech structure) within this volume.
//
//             WGS: new class EMECConstruction for GeoModel application created
//  EMECConstruction:
// 06-Oct-2003 J.T. code revised to work in the GeoModel framework
// 06-Oct-2003 J.T. EMEC Mother volume z limits corrected for cold values.
// 06-Oct-2003 J.T. crossing of volume of top indexing ring and stretchers
//                  corrected.
// 21-Jul-2005 C.S. Revised to take into account changes in G4 simulation
// 18-Sep-2006 V.N. Put back options for TB module
// 18-Sep-2006 V.N  Get materials from LarMaterialManager
// May-June 2009 AMS Get most part of geometry constants from LArWheelCalculator
//                   General code cleanup
// Feb 2022 JFB Since the appearance of the GeoUnidentifiedShape, the LArCustomShape
//              class is deprecated. We therefore decouple this package from 
//              GeoSpecialShapes, computing a few constants here which were previously
//              taken from the calculator.
