// G4Box
//
// Class description:
//
// A Box is a cuboid of given half lengths dx,dy,dz. The Box is
// centred on the origin with sides parallel to the x/y/z axes.
// 30.06.95 P.Kent: Converted from source code developed end 94
// 27.03.96 J.Allison: Added virtual functions DescribeYourselfTo() and
// SendWireframeTo(G4VGraphicsModel&)
// 27.03.98 J.Apostolakis: Inherit from G4CSGSolid (not G4VSolid)
