Class Description :

  
  
   G4ExtrudedSolid is a solid which represents the extrusion of an arbitrary
   polygon with fixed outline in the defined Z sections.
   The z-sides of the solid are the scaled versions of the same polygon.
   The solid is implemented as a specification of G4TessellatedSolid.
    
   Parameters in the constructor:
   const G4String& pName             - solid name
   std::vector polygon  - the vertices of the outlined polygon
                                       defined in clockwise or anti-clockwise order     
   std::vector             - the z-sections defined by
                                       z position, offset and scale
                                       in increasing z-position order
  
   Parameters in the special constructor (for solid with 2 z-sections:
   G4double halfZ                    - the solid half length in Z
   G4TwoVector off1                  - offset of the side in -halfZ
   G4double scale1                   - scale of the side in -halfZ
   G4TwoVector off2                  - offset of the side in +halfZ
   G4double scale2                   - scale of the side in -halfZ
