// The following is based on G4PVDivision of Gean4 as of 4/2004
//
// The elements' positions are calculated by means of a simple
// linear formula.
// 
// G4PVDivision(const G4String& pName,
//                    G4LogicalVolume* pLogical,
//                    G4LogicalVolume* pMother,
//              const EAxis pAxis,
//              const G4int nReplicas,
//              const G4double width,
//              const G4double offset=0)
//
// 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

// GEANT4 History:
// 09.05.01 - P.Arce Initial version
//
// DDD History:
// 13.04.04 - M. Case Initial DDD version.
