+ns3wimax.py - This script demonstrates using CORE with the ns-3 Wimax model.
+*** Note that this script is not currently functional, see notes below. ***
+Current issues:
+- large amount of base station chatter; huge trace files, 70% CPU usage
+- PCAP files unreadable
+- base station causes segfault if it sends packet; due to missing service flows
+  (but AddFlow() is not available for bs devices)
+- no packets are sent between nodes - no connection?
