The `MultiBlock` class has been renamed to `PartitionedDataSet`, and its API has been refactored to refer to "partitions", rather than "blocks". Additionally, the `AddBlocks` method has been changed to `AppendPartitions` to more accurately reflect the operation performed. The associated `AssignerMultiBlock` class has also been renamed to `AssignerPartitionedDataSet`. This change is motivated towards unifying VTK-m's data model with VTK. VTK has started to move away from `vtkMultiBlockDataSet`, which is a hierarchical tree of nested datasets, to `vtkPartitionedDataSet`, which is always a flat vector of datasets used to assist geometry distribution in multi-process environments. This simplifies traversal during processing and clarifies the intent of the container: The component datasets are partitions for distribution, not organizational groupings (e.g. materials). Ref #405
