This is an example of how to use the limiting actions.
It requires a SICK laser. Use either a joystick or keyboard
to drive the robot. If the SICK laser detects obstacles, actions
slow down the robot as it approaches.
The way it works is that it has a limiting behavior higher priority
than the joydrive and keydrive actions. So if the limiting behaviors
detect obstacles that are too close, they set speed limits proportional
to the distance that slow down the robot and eventually prevent the
joydrive and keydrive actions from having any effect on the robot.
