// .NAME vtkSectorSource - create a sector of a disk
// .SECTION Description
// vtkSectorSource creates a sector of a polygonal disk. The 
// disk has zero height. The user can specify the inner and outer radius
// of the disk, the z-coordinate, and the radial and 
// circumferential resolution of the polygonal representation. 
// .SECTION See Also
// vtkLinearExtrusionFilter
