// .NAME vtkMutableGraphHelper - Helper class for building a directed or
// directed graph
//
// .SECTION Description
// vtkMutableGraphHelper has helper methods AddVertex and AddEdge which
// add vertices/edges to the underlying mutable graph. This is helpful in
// filters which need to (re)construct graphs which may be either directed
// or undirected.
//
