GRLABEL Associate a label to each connected component of the graph.

   LABELS = grLabel(NODES, EDGES)
   Returns an array with as many rows as the array NODES, containing index
   number of each connected component of the graph. If the graph is
   totally connected, returns an array of 1.

   Example
       nodes = rand(6, 2);
       edges = [1 2;1 3;4 6];
       labels = grLabel(nodes, edges);
   labels =
       1
       1
       1
       2
       3
       2
