+ * which makes the ring, any given number is multiplied by
+ * the log of the network size; i.e. a PERCENTAGE of 2 makes
+ * each peer have on average 2logn connections. The additional
+ * connections are made at increasing distance around the ring
+ * from the original peer, or to random peers based on the re-
+ * wiring probability. The TESTING
