 * This interface is implemented as a marker by drones.

 * <pre>
 *     if (entity instanceof Drone) {
 * </pre>

 * The only purpose is to allow identifying entities as drones via the API,
 * i.e. without having to link against internal classes. This also means
 * that <em>you should not implement this</em>.
