SoTimerSensor — sensor that triggers callback repeatedly at regular intervals

       Timer  sensors  trigger their callback function at regular intervals. For example, a timer might be setup
       to call its callback function every second on the second by setting the base time to SbTime(0.0) and  the
       interval  to  SbTime(1.0).  Timers  are  guaranteed  to  be  triggered  only once when the timer queue is
       processed, so if the application only processes the timer queue once every 5 seconds (because it is  busy
       doing something else) the once-a-second sensor's callback will be called only once every 5 seconds.

       Note also that SoTimers always schedule themselves to be triggered the next even multiple of the interval
       time  after the base time; so, for example, if the once-a-second sensor is triggered at time 2.9 (because
       the application way busy doing something at time 2.0 and didn't get around to processing the sensor queue
       for a while) it will reschedule itself to go off at time 3.0, not at time 3.9. If the base time was never
       set, the sensor would be scheduled for time 3.9.

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

                         ~SoTimerSensor()
          Destroys the sensor, freeing up any memory associated with it after unscheduling it.

     voidsetBaseTime(constSbTime&base)constSbTime&getBaseTime()constvoidsetInterval(constSbTime&interval)constSbTime&getInterval()const
          Sets/gets  the  base  time  and  the  interval.  The  default base time is the time when the sensor is
          scheduled or rescheduled, and the default interval is 1/30th of a second.
