// .NAME vtkVertexListIterator - Iterates all vertices in a graph.
//
// .SECTION Description
// vtkVertexListIterator iterates through all vertices in a graph.
// Create an instance of this and call graph->GetVertices(it) to initialize
// this iterator. You may alternately call SetGraph() to initialize the
// iterator.
