The goal of this exercise is to create an http.Handler that will look at the path of any incoming web request and determine if it should redirect the user to a new page, much like URL shortener would.
For instance, if we have a redirect setup for /dogs to https://www.somesite.com/a-story-about-dogs we would look for any incoming web requests with the path /dogs and redirect them.
