What is being done here is having 8 peers all connect to eachother and be
connected. Then it check if they all connect. If so send data in ordered reliable mode for 100
loops.
Possible ideas for changes:
Possibly use rakpeerinterfaces GetSystemList() for number of
connected peers instead of manually tracking. Would be slower though,
shouldn't be significant at this number but the recieve speed it part of the test.
Success conditions:
Peers connect and receive all packets in order.
No disconnections allowed in this version of the test.
Failure conditions:
If cannot connect to all peers for 20 seconds.
All packets are not recieved.
All packets are not in order.
Disconnection.
