 * @class   vtkDataSetRegionSurfaceFilter
 * @brief   Extract surface of materials.
 *
 * 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.
