// .NAME vtkLabelHierarchyAlgorithm - Superclass for algorithms that produce only label hierarchies as output
// .SECTION Description
//
// vtkLabelHierarchyAlgorithm is a convenience class to make writing algorithms
// easier. It is also designed to help transition old algorithms to the new
// pipeline architecture. There are some assumptions and defaults made by this
// class you should be aware of. This class defaults such that your filter
// will have one input port and one output port. If that is not the case
// simply change it with SetNumberOfInputPorts etc. See this class
// constructor for the default. This class also provides a FillInputPortInfo
// method that by default says that all inputs will be DataObjects. If that
// isn't the case then please override this method in your subclass. This
// class breaks out the downstream requests into separate functions such as
// RequestData and RequestInformation. You should
// implement RequestData( request, inputVec, outputVec) in subclasses.
