Finishing the traffic analyzer

The program works, all we have to do is make the interface friendlier and add recommendations for Muffin.

But first, indicate the value that is logged in the console. Muffin should be able see that it is the average value, and not something else.

Then you need to compare the average value with the expected one and show Muffin the recommendation. If the traffic is good (the average value is greater than the expected one), then cheer the cat up, if not, ask him to work harder and start putting out better content.
