These file contain code that can be used to convert REAL from a single
node simulator to a multi-node simulator.  The idea is that if a node
wants to send a packet to a node on another computer (or address space),
it sends it to a dummy node call cc_router instead. This node will
then convert the REAL packet to a real packet and send it on a 
socket to a coordination master. When the master has received 
packets from all the slave cc_routers, it will route them to them
to the correct REAL node, and send a proceed signal to all the 
slaves. The slaves then convert the real packets to REAL packets and
ship them to the appropriate node. 

The scheme works, but has a large communication overhead. Moreover,
all the simulations will proceed at the same speed as the slowest one.
So, in practice distributes simulation is not a win.

But, I wrote all this code, and maybe someone can use it.
