// .NAME vtkLabelHierarchyCompositeIterator - Iterator over sub-iterators
//
// .SECTION Description
// Iterates over child iterators in a round-robin order. Each iterator may
// have its own count, which is the number of times it is repeated until
// moving to the next iterator.
//
// For example, if you initialize the iterator with
// <pre>
// it->AddIterator(A, 1);
// it->AddIterator(B, 3);
// </pre>
// The order of iterators will be A,B,B,B,A,B,B,B,...
