Class Description

 TGeoHype - Hyperboloid class defined by 5 parameters. Bounded by:
            - Two z planes at z=+/-dz
            - Inner and outer lateral surfaces. These represent the surfaces 
              described by the revolution of 2 hyperbolas about the Z axis:
               r^2 - (t*z)^2 = a^2

            r = distance between hyperbola and Z axis at coordinate z
            t = tangent of the stereo angle (angle made by hyperbola
                asimptotic lines and Z axis). t=0 means cylindrical surface.
            a = distance between hyperbola and Z axis at z=0

          The inner hyperbolic surface is described by:
              r^2 - (tin*z)^2 = rin^2 
           - absence of the inner surface (filled hyperboloid can be forced 
             by rin=0 and sin=0
          The outer hyperbolic surface is described by:
              r^2 - (tout*z)^2 = rout^2
  TGeoHype parameters: dz[cm], rin[cm], sin[deg], rout[cm], sout[deg].
    MANDATORY conditions:
           - rin < rout
           - rout > 0
           - rin^2 + (tin*dz)^2 > rout^2 + (tout*dz)^2
           - rin = 0, tin != 0     => inner surface conical
           - tin=0 AND/OR tout=0   => corresponding surface(s) cyllindrical
             e.g. tin=0 AND tout=0 => shape becomes a tube with: rmin,rmax,dz
