Class Description

 TGeoArb8 - a arbitrary trapezoid with less than 8 vertices standing on
   two paralel planes perpendicular to Z axis. Parameters :
            - dz - half length in Z;
            - xy[8][2] - vector of (x,y) coordinates of vertices
               - first four points (xy[i][j], i<4, j<2) are the (x,y)
                 coordinates of the vertices sitting on the -dz plane;
               - last four points (xy[i][j], i>=4, j<2) are the (x,y)
                 coordinates of the vertices sitting on the +dz plane;
   The order of defining the vertices of an arb8 is the following :
      - point 0 is connected with points 1,3,4
      - point 1 is connected with points 0,2,5
      - point 2 is connected with points 1,3,6
      - point 3 is connected with points 0,2,7
      - point 4 is connected with points 0,5,7
      - point 5 is connected with points 1,4,6
      - point 6 is connected with points 2,5,7
      - point 7 is connected with points 3,4,6
   Points can be identical in order to create shapes with less than
   8 vertices.

 in case shape has some negative parameters, these has to be computed
 in order to fit the mother
