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