// class G4ReplicatedSlice
//
// Class description:
//
// G4ReplicatedSlice represents many touchable detector elements differing
// only in their positioning. The elements' positions are calculated by means
// of a simple linear formula.
// 
// Division may occur along:
//
// o Cartesian axes (kXAxis,kYAxis,kZAxis)
//
//   The divisions, of specified width have coordinates of
//   form (-width*(nReplicas-1)*0.5+n*width,0,0) where n=0.. nReplicas-1
//   for the case of kXAxis, and are unrotated.
//
// o Radial axis (cylindrical polar) (kRho)
//
//   The divisions are cons/tubs sections, centred on the origin
//   and are unrotated.
//   They have radii of width*n+offset to width*(n+1)+offset
//                      where n=0..nReplicas-1
//
// o Phi axis (cylindrical polar) (kPhi)
//   The divisions are `phi sections' or wedges, and of cons/tubs form
//   They have phi of offset+n*width to offset+(n+1)*width where
//   n=0..nReplicas-1
