// Class G4AssemblyTriplet
//
// Class description:
//
// A class to help place logical or assembly volumes inside a generic 
// containers (like STL vector ) together with information about its rotation, 
// placement and eventually reflection.
// How to interpret the rotation and translation depends on the class which
// uses a container of these triplets. The first class using G4AssemblyTriplet
// is G4AssemblyVolume class.
// The pointer to the logical or assembly volume is copied so this class 
// does not take its ownership and does not delete the object behind.

// Author:      Radovan Chytracek
// Version:     1.0
// Date:        November 2000
//
// History:
// March 2006, I.Hrivnacova - Extended to support assembly of assemblies
//             of volumes and reflections
