* This node is part of the RPL multicast example. It basically
* represents a node that does not join the multicast group
* but still knows how to forward multicast packets
* The example will work with or without any number of these nodes
*
* Also, performs some sanity checks for the contiki configuration
* and generates an error if the conf is bad
