+@brief feature/stats: Relay statistics. Also, port prediction.
+
+This module collects anonymized relay statistics in order to publish them in
+relays' routerinfo and extrainfo documents.
+
+Additionally, it contains predict_ports.c, which remembers which ports we've
+visited recently as a client, so we can make sure we have open circuits that
+support them.
