GRREMOVENODES Remove several nodes in a graph.

   usage:
   [NODES2 EDGES2] = grRemoveNodes(NODES, EDGES, NODES2REMOVE)
   remove the nodes with indices NODE2REMOVE from array NODES, and also
   remove edges containing the nodes NODE2REMOVE.

   Example
     nodes = [...
         10 10; 20 10; 30 10; ...
         10 20; 20 20; 30 20];
     edges = [...
         1 2; 1 4; 1 5; ...
         2 3; 2 5; 2 6; ...
         3 6; 4 5; 5 6];
     toRemove = [3 4];
     [nodes2 edges2] = grRemoveNodes(nodes, edges, toRemove);
     drawGraph(nodes2, edges2);
     axis equal; axis([0 40 0 30]);
