// Multigraph class

// A Multigraph contains a collection of Vertex objects, each of which
// maintains its own adjacency list of edges (see the Vertex and Edge 
// classes).

// To enumerate the vertices in the Multigraph, you can simply ask for
// the number of vertices n, then call get() successively on 0 .. n-1.
