// .NAME vtkXMLRectilinearGridWriter - Write VTK XML RectilinearGrid files.
// .SECTION Description
// 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.
