PRUNEGRAPH Remove all edges with a terminal vertex.

   [NODES2, EDGES2] = pruneGraph(NODES, EDGES)

   Example
     nodes = [...
         10 30; 30 30; 20 45; 50 30; 40 15; 70 30; 90 30; 80 15; 100 45];
     edges = [1 2;2 3;2 4;4 5;4 6;6 7;6 8;7 8;7 9];
     figure; 
     subplot(2, 1, 1); drawGraph(nodes, edges); 
     axis equal; axis([0 110 10 50]);
     [nodes2, edges2] = pruneGraph(nodes, edges);
     subplot(2, 1, 2); drawGraph(nodes2, edges2); 
     axis equal; axis([0 110 10 50]);
