* @class vtkXMLPartitionedDataSetReader
* @brief Reader for partitioned datasets
*
* vtkXMLPartitionedDataSetReader reads the VTK XML partitioned dataset file
* format. XML partitioned dataset files are meta-files that point to a list
* of serial VTK XML files. When reading in parallel, it will distribute
* sub-blocks among processors. If the number of sub-blocks is less than
* the number of processors, some processors will not have any sub-blocks
* for that block. If the number of sub-blocks is larger than the
* number of processors, each processor will possibly have more than
* 1 sub-block.
