/* This module provides statistics about two merged capture files, to find packet loss,
* time delay, ip header checksum errors and order check.
* It's also detecting the matching regions of the different files.
* After the coloring is set Info column can be sorted to create zebra effect.
*
* The packets are compared by the ip id. MAC or TTL is used to distinct the different files.
