*
* vtkXMLUnstructuredGridWriter writes the VTK XML UnstructuredGrid
* file format. One unstructured grid input can be written into one
* file in any number of streamed pieces (if supported by the rest of
* the pipeline). The standard extension for this writer's file
* format is "vtu". This writer is also used to write a single piece
* of the parallel file format.
