// Class G4ReflectionFactory Implementation
//
// Decomposition of a general transformation
// that can include reflection in a "reflection-free" transformation:
//
// x(inM') = TG*x(inM) TG - general transformation
// = T*(R*x(inM)) T - "reflection-free" transformation
// = T* x(inReflM)
//
// Daughters transformation:
// When a volume V containing daughter D with transformation TD
// is placed in mother M with a general tranformation TGV,
// the TGV is decomposed,
// new reflected volume ReflV containing a new daughter ReflD
// with reflected transformation ReflTD is created:
//
// x(inV) = TD * x(inD);
// x(inM) = TGV * x(inV)
// = TV * R * x(inV)
// = TV * R * TD * x(inD)
// = TV * R*TD*R-1 * R*x(inD)
// = TV * ReflTD * x(inReflD)
