* \brief a RandomDirection mobility model
*
* The movement of objects is based on random directions: each object
* pauses for a specific delay, chooses a random direction and speed and
* then travels in the specific direction until it reaches one of
* the boundaries of the model. When it reaches the boundary, it pauses,
* selects a new direction and speed, aso.
