[ns] Trace File - - - which data represent packet id

[Sasan Sahraei]

The way I calculate the overall simulation avg end-to-end delay is the SUM
of all transmission time framce within the whole simulation (end  - start
per flows/packet ids) over total number of data packets received.

start[packetid] = time
end[packetid] = time

and for all packets

(sum of all end[packetid] - starts[packetid]) / total_data_packets_received

note that it is data packets recieved and do NOT count routed data packets.

unless you are counted the delay per flow.
