GRAPHDIAMETER Diameter of a graph.

   D = graphDiameter(V, E)
   Computes the diameter of the graph given by V and E. The diameter of
   the graph is the greatest eccentricity over all vertices in the graph.

   D = graphDiameter(V, E, L)
   Specifies the weight of each edge for computing the distances. Default
   is to consider a weight of 1 for each edge.

   Example
     nodes = [20 20;20 50;20 80;50 50;80 20;80 50;80 80];
     edges = [1 2;2 3;2 4;4 6;5 6;6 7];
     figure; drawGraph(nodes, edges);
     axis([0 100 0 100]); axis equal; hold on
     D = graphDiameter(nodes, edges)
     D = 
         4
