Class Description

 HGeomTrd1

 class for the GEANT shape TRD1

 The technical coordinate system of a TRD1, which sits in
 CAVE and is not rotated, is the laboratory system.
 The y-axis points from the smaller side to the larger one.
 That's the same definitition as for a TRAP and different from
 the Geant or ROOT definition for a TRD1.
 Therefore a transformation is needed:
              x-technical = - (x-Geant)
              y-technical = z-Geant
              z-technical = y-Geant
 This is stored in the data element intrinsicRot which is
 created in the function calcVoluPosition(...)

 constructor

 destructor

 calculates the parameters needed to create the shape

 calls the function posInMother(...) to calculate the position of the
 volume in its mother
