/**
 *  SoPolyhedron is an Inventor encapsulation of the G4Polyedron
 * class written by E.Chernyaev. In particular SoPolyhedron permits
 * to represent boolean operations over solids.
 *  To avoid clashes with other libraries (Geant4) where the G4Polyhedron
 * classes may be found, the G4Polyhedron (through usage of CPP macros)
 * had been renamed G4Polyhedron in the HEPVis lib.
 *  The solids are modeled with G4Polyedron objects. The G4Polyhedron
 * permits to produce a new G4Polyhedron according to the boolean 
 * operation done on them. The resulting G4Polyhedron  is then given
 * to an SoPolyhedron for rendering.
 *  Note that a boolean operation could be rendered in wire frame
 * by drawing the contour of the resulting solid (not by drawing
 * the wire frame of a triangulation).
 *  See the applications/Polyhedron example.
