XBee configuration

The Xbee modules have been configured and talk to each other. The topology we are using is a ZigBee mesh, with 6 Routers and 1 Coordinator. The XBees are running in Transparent mode, so it's just a very simple text transmission, no bells and whistles. Basic code to interface with them will be tested this weekend - the rest of the development will be handed over to the Command and Control team. More specifications to follow.
