/**
* @class vtkXMLPUnstructuredGridReader
* @brief Read PVTK XML UnstructuredGrid files.
*
* vtkXMLPUnstructuredGridReader reads the PVTK XML UnstructuredGrid
* file format. This reads the parallel format's summary file and
* then uses vtkXMLUnstructuredGridReader to read data from the
* individual UnstructuredGrid piece files. Streaming is supported.
* The standard extension for this reader's file format is "pvtu".
