Overview

Here we store all of the packet loss and latency data for each host. We store the packets using a ring buffer so we can keep track of the last 100 and 1000 packets. We also store the total number of packets dropped.

This is mostly an attempt for me to use a complicated memory struct vs a more standard slice.
