test program

This test program does some manipulation of the topology and uses the dynamic
features of global routing to change the global routing tables.

//  Order of events
//  At pre-simulation time, configure global routes.  Shortest path from
//  n1 to n6 is via the direct point-to-point link
//  At time 1s, start CBR traffic flow from n1 to n6
//  At time 2s, set the n1 point-to-point interface to down
//  At time 3s, call RecomputeGlobalRoutes() and traffic will
//    start flowing again on the alternate path
//  At time 4s, re-enable the n1/n6 interface to up.  Will not change routing
//  At time 5s, call RecomputeGlobalRoutes() and traffic will start flowing 
//    again on the original path
