* vtkXMLStructuredGridReader reads the VTK XML StructuredGrid file
* format. One structured grid file can be read to produce one
* output. Streaming is supported. The standard extension for this
* reader's file format is "vts". This reader is also used to read a
* single piece of the parallel file format.
