 Injection of pre-defined sensor errors should be handled by a specialized "fault injector" component that acts like a
 sensor model component, i.e. it takes a SensorData message as input and returns a modified SensorData message as output.
 Specific errors should be handled as follows:

       should respect this flag and never reset an object marked as not-seen to seen.
