32 // Class description:
33 //
34 // Class representing a single volume positioned within and relative
35 // to a mother volume.
36 
37 // History:
38 // 24.07.95 P.Kent First non-stub version
39 // 25.07.96 P.Kent Modified interface for new `Replica' capable geometry
40 // 28.08.96 P.Kent Tidied + transform replaced by rotmat+vector
41 // 28.02.97 J.Apostolakis Added 2nd constructor with G4Transform3D of solid.
42 // 11.07.97 J.Apostolakis Added 3rd constructor with pMotherLogical
43 // 11.05.98 J.Apostolakis Added 4th constructor with G4Transform3D & pMotherLV
