SoAlarmSensor — triggers a callback once sometime in the future

       This  type  of sensor can be used to schedule a one-time callback for some time in the future. The sensor
       is not guaranteed to be called at exactly that time, but will be  called  sometime  after  the  specified
       time.

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

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

     voidsetTime(constSbTime&absTime)
          Sets the sensor to go off at the specified time. You must also call schedule() for the  sensor  to  be
          triggered.  If  the  sensor  is already scheduled, it must be unscheduled and then rescheduled for the
          change in the trigger time to take effect.

     voidsetTimeFromNow(constSbTime&relTime)
          Sets the sensor to go off the given amount of time from now. You must also  call  schedule()  for  the
          sensor  to  be  triggered.  If  the  sensor  is  already  scheduled,  it  must be unscheduled and then
          rescheduled for the change in the trigger time to take effect.

     constSbTime&getTime()const
          Returns the time at which the sensor is set to be triggered. This is  similar  to  the  getTriggerTime
          method, but returns the time even if the sensor has not yet been scheduled.
