Detailed Description

This model is exciting enough so that we can collect some statistics. We'll record in output vectors the hop count of every message upon arrival. Output vectors are written into the omnetpp.vec file and can be visualized with the Plove program.

We also collect basic statistics (min, max, mean, std.dev.) and histogram about the hop count which we'll print out at the end of the simulation.
