### Data Members

## Class Description

     PGON is a polygon. It has the following parameters:

         - name       name of the shape
         - title      shape's title
         - material  (see TMaterial)
         - phi1       the azimuthal angle &phi at which the volume begins (angles
                      are counted counterclockwise)
         - dphi1      opening angle of the volume, which extends from phi1 to
                      phi1+dphi
         - npdv       number of sides of the cross section between the given
                      phi limits
         - nz         number of planes perpendicular to the z axis where
                      the dimension of the section is given -- this number
                      should be at least 2
         - rmin       array of dimension nz with minimum radius at a given plane
         - rmax       array of dimension nz with maximum radius at a given plane
         - z          array of dimension nz with z position of given plane
