jar copying working now; adjusted default value for glassfish directory to point to 4.1 rather than 4.0
format source
change reference to VehicleFactory to CompositeVehicleFactory (VehicleFactory doesn't have an implementation)
added missing @Stateless annotations for implementations of GPS interferers
adding missing default constructor for EJB conformity
CompositeGpsInterferer can't be an EJB, wouldn't make sense anyway, use as container for references to other GPS interferers
