* @class vtkXMLPImageDataReader

*
* vtkXMLPImageDataReader reads the PVTK XML ImageData file format.
* This reads the parallel format's summary file and then uses
* vtkXMLImageDataReader to read data from the individual ImageData
* piece files. Streaming is supported. The standard extension for
* this reader's file format is "pvti".
