//
// Class description:
//
// An abstraction of a geometrical surface, it is an abstract 
// base class for different implementations of surfaces.
// Its primary function is to hold pointers to objects that describe the
// surface's physical properties. For example it holds a pointer to a
// surface's optical properties, and because of this it is used in processes
// like G4OpBoundaryProcess. 
//
// Methods:
//   G4SurfaceProperty*  GetSurfaceProperty() const
//   void     SetSurfaceProperty(G4SurfaceProperty*)
//
//   G4String GetName() const
//   void     SetName(const G4String&)
//
//   G4TransitionRadiationSurface*  GetTransitionRadiationSurface() const
//   void SetTransitionRadiationSurface(G4TransitionRadiationSurface*)
//
// Data members:
//   G4String                       theName
//   G4SurfaceProperty*             theSurfaceProperty
//   G4TransitionRadiationSurface*  theTransRadSurface
