37// Class description:
38//
39// G4ExtrudedSolid is a solid which represents the extrusion of an arbitrary
40// polygon with fixed outline in the defined Z sections.
41// The z-sides of the solid are the scaled versions of the same polygon.
42// The solid is implemented as a specification of G4TessellatedSolid.
43// 
44// Parameters in the constructor:
45// const G4String& pName             - solid name
46// std::vector<G4TwoVector> polygon  - the vertices of the outlined polygon
47//                                     defined in clockwise or anti-clockwise order     
48// std::vector<ZSection>             - the z-sections defined by
49//                                     z position, offset and scale
50//                                     in increasing z-position order
51//
52// Parameters in the special constructor (for solid with 2 z-sections:
53// G4double hz                       - the solid half length in Z
54// G4TwoVector off1                  - offset of the side in -hz
55// G4double scale1                   - scale of the side in -hz
56// G4TwoVector off2                  - offset of the side in +hz
57// G4double scale2                   - scale of the side in -hz
