Summary:                    composite data set iterator seems buggy with
vtkOverlappingAMR
Description: 
If you run the following code snippet, 

  vtkNew<vtkAMRGaussianPulseSource> imageSource;
  imageSource->Update();

  vtkOverlappingAMR* amr =
vtkOverlappingAMR::SafeDownCast(imageSource->GetOutputDataObject(0));
  vtkCompositeDataIterator * iter = amr->NewIterator();
  iter->InitTraversal();
  while ( !iter->IsDoneWithTraversal() )
    {
    vtkAMRBox box =amr->GetAMRBox(iter);
    vtkUniformGrid* grid =
vtkUniformGrid::SafeDownCast(iter->GetCurrentDataObject());
    assert(grid);
    int numCells = grid->GetNumberOfCells();
    cout<<"AMR box info: "<<"level "<<box.GetLevel()<<", Block:
"<<box.GetBlockId()<<endl;
    iter->GoToNextItem();
    }

You get the output:

AMR box info: level 0, Block: 0
AMR box info: level 0, Block: 0
AMR box info: level 0, Block: 1

Notice that the first and the second block has identical (level, block) pair.
This is not right.
