Python parsing qualnet. Trace [XML parsing]

Statistics on the total throughput/average latency/real-time throughput of each stream in qualnet. Trace should be useful for qualnet simulation.

Using lxml for parsing, the memory usage is half that of the built-in elementtree, and the speed is superb.

It is better to use the data stored in dict to change it to a class, but it is not difficult to change it. You can use it.
