37// Class description:
38//
39// Class implmenting a face that represents one conical side
40// of a polycone:
41//
42// G4PolyconeSide( const G4PolyconeSideRZ *prevRZ,
43// const G4PolyconeSideRZ *tail,
44// const G4PolyconeSideRZ *head,
45// const G4PolyconeSideRZ *nextRZ,
46// G4double phiStart, G4double deltaPhi,
47// G4bool phiIsOpen, G4bool isAllBehind=false )
48//
49// Values for r1,z1 and r2,z2 should be specified in clockwise
50// order in (r,z).
