// .NAME vtkDataSetRegionSurfaceFilter - Extract surface of materials.
// .SECTION Description
// This filter extracts surfaces of materials such that a surface
// could have a material on each side of it. It also stores a
// mapping of the original cells and their sides back to the original grid
// so that we can output boundary information for those cells given
// only surfaces.
