[ns] velocity and direction of mobile nodes

[Erico Augusto]

The path to one of that generators is:

ns-allinone-2.xxxx/ns-2.xxx/indep-utils/cmu-scen-gen/setdest/setdest


Executing it with:
setdest -v 1 -n 3 -p 5.0 -M 10 -t 100 -x 1000 -y 1000 > 3.scen
yields file 3.scen,with the following content:

#
# nodes: 3, pause: 5.00, max speed: 10.00, max x: 1000.00, max y: 1000.00
