/** @example gotoActionExample.cpp Uses ArActionGoto to drive the robot in a square
This program will make the robot drive in a 2.5x2.5 meter square by
setting each corner in turn as the goal for an ArActionGoto action.
It also uses speed limiting actions to avoid collisions. After some
time, it cancels the goal (and the robot stops due to a stopping action)
and exits.
Press escape to shut down Aria and exit.
