 * vtkXMLRectilinearGridWriter writes the VTK XML RectilinearGrid
 * file format.  One rectilinear grid input can be written into one
 * file in any number of streamed pieces.  The standard extension for
 * this writer's file format is "vtr".  This writer is also used to
 * write a single piece of the parallel file format.
