Set of vertices
Set of vertices. A set of vertices is a vertex, but it represents several vertices.This class is useful to easily manipulate graphs that are built by merging several vertices into one. For example, each vertex can represent a strongly component of a graph, or all vertices that belong to a given set, etc. Each set has an internal color. See also the class NstGraph for more details.
