DESCRIPTION
     Path sensors detect changes to paths, calling a callback function
     whenever the path or any node in the path changes. The definition of "in
     the path" is the same as the definition used when applying an action to
     the path - any node that can possibly affect the node at the end of the
     path chain is considered in the path. See the SoPath manual page for more
     information on paths.

FUNCTIONS
     SoPathSensor *	 SoPathSensCreate()
     SoPathSensor *	 SoPathSensCreateCB(SoSensorCB *func, void *data)
	  Creation methods. The second method takes the callback function and
	  data to be called when the sensor is triggered.

     void		 SoPathSensDelete(SoPathSens *this)
	  Destroys the sensor, freeing up any memory associated with it after
	  unscheduling it.

     void		 SoPathSensAttach(SoPathSens *this, SoPath *path)
     void		 SoPathSensDetach(SoPathSens *this)
     SoPath *		 SoPathSensGetAttachedPath(const SoPathSens *this)
	  The attach() method makes this sensor detect changes to the given
	  path. The detach() method unschedules this sensor (if it is
	  scheduled) and makes it ignore changes to the scene graph. The
	  getAttachedPath() method returns the path that this sensor is
	  sensing, or NULL if it is not attached to any path.
