class TGeoSphere: public TGeoBBox

 TGeoSphere - spherical shell class. It takes 6 parameters :
           - inner and outer radius Rmin, Rmax
           - the theta limits Tmin, Tmax
           - the phi limits Pmin, Pmax (the sector in phi is considered
             starting from Pmin to Pmax counter-clockwise
