// .NAME vtkHyperOctreePointsGrabber - An object used by filters to
// store points computed on face or edge of an hyperoctant. It is an
// abstract class. vtkClipHyperOctree and vtkHyperOctreeCutter use
// vtkHyperOctreeClipCutPointsGrabber
// vtkHyperOctreeContourFilter use an internal one:
// vtkHyperOctreeContourFilterPointsGrabber.
// .SECTION See Also
// vtkHyperOctree, vtkHyperOctreeClipCutPointsGrabber,

// that lie on an hyperoctant.
