// .NAME vtkMultiBlockDataSet - Composite dataset that organize datasets in blocks
// .SECTION Description
// vtkMultiBlockDataSet is a vtkCompositeDataSet that stores
// a hierarchy of datasets. The dataset collection consists of
// multiple blocks. Each block can have zero or more sub-blocks.
// Sub-blocks are usually used to distribute blocks across processors.
// For example, a 1 block dataset can be distributed as following:
// @verbatim
// proc 0:
// Block 0:
// * ds 0
// * (null)
//
// proc 1:
// Block 0:
// * (null)
// * ds 1
// @endverbatim
//
// The levels are implemented as groups (see vtkMultiGroupDataSet) and can
// be treated as such. This allows the use of all vtkMultiGroupDataSet.
// Currently, the interface for connecting parents-children is incomplete.
//
