Output plotting

[aman-agarwal]

Real time plotting needs to be implemented.
Also, the plots need to be formatted better (including headings, units, readability).

@adbh94 @aman-agarwal It makes more sense for flow_send_rate, flow_receive_rate,host_send_rate,host_receive_rate to be in Mbps instead of pkts/s? Since packets can have different sizes

@aman-agarwal also if you are implementing window size, can you add report for this param too?
