/**
* This interface is used to receive notification each time the GPS transmits one of the common data, ie. position, time and date.
* <ul>
* <li> The GPS does not necessarily transmit these things periodially by itself! Some GPS-units needs a request before 
* transmitting anything. Use the method GPS.setAutoTransmission(true) if you want the GPS to periodically send this data.
* <li> Don't perform any long calculations or big operations in these methods. They're called by a dispatching thread, and putting 
* it to too much work will slow performance on the communication with the GPS.
