made saved data tableview cells not reusable to fix the image cell problem. changed the order in which the data appears in the cells so gps stuff is on bottom. made gps delegate methods optional. updated the gsfgeotagger class so that it won’t be collecting forever as long as it has at least 5 readings in the buffer and 1 is set the the best effort.
