// .NAME vtkXMLRectilinearGridReader - Read VTK XML RectilinearGrid files.
// .SECTION Description
// vtkXMLRectilinearGridReader reads the VTK XML RectilinearGrid file
// format. One rectilinear grid file can be read to produce one
// output. Streaming is supported. The standard extension for this
// reader's file format is "vtr". This reader is also used to read a
// single piece of the parallel file format.
