// .NAME vtkHyperOctreeToUniformGridFilter - Flat the octree into a uniform
// grid
// .SECTION Description
// vtkHyperOctreeToUniformGridFilter creates a uniform grid with a resolution
// based on the number of levels of the hyperoctree. Then, it copies celldata
// in each cell of the uniform grid that belongs to an actual leaf of the
// hyperoctree.
//
// .SECTION See Also
// vtkGeometryFilter vtkStructuredGridGeometryFilter.
