/**
* @class vtkCompositeDataSet
* @brief abstract superclass for composite
* (multi-block or AMR) datasets
*
* vtkCompositeDataSet is an abstract class that represents a collection
* of datasets (including other composite datasets). It
* provides an interface to access the datasets through iterators.
* vtkCompositeDataSet provides methods that are used by subclasses to store the
* datasets.
* vtkCompositeDataSet provides the datastructure for a full tree
* representation. Subclasses provide the semantics for it and control how
* this tree is built.
