// .NAME vtkHierarchicalBoxDataSet - hierarchical dataset of vtkUniformGrids
// .SECTION Description
// vtkHierarchicalBoxDataSet is a concrete implementation of  
// vtkHierarchicalDataSet. The dataset type is restricted to
// vtkUniformGrid. Each dataset has an associated vtkAMRBox
// that represents it's region (similar to extent) in space.
