/**
* @class vtkGraphAlgorithm
* @brief Superclass for algorithms that produce only graph as output
*
*
* vtkGraphAlgorithm 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 Graph. If that
* isn't the case then please override this method in your subclass.
* You should implement the subclass's algorithm into
* RequestData( request, inputVec, outputVec).
*
* @par Thanks:
* Thanks to Patricia Crossno, Ken Moreland, Andrew Wilson and Brian Wylie from
* Sandia National Laboratories for their help in developing this class.
