Test app reloading

The compojure template added several middleware functions to our project to make the webapp easier to work with. The wrap-reload middleware picks up changes to our code and will automatically load them into our running webapp. This provides rapid feedback on your coding.

Note:: Make a simple change to the app-routes function in src/shorturl-service/handler.clj file, eg. change the "Hello World" string to "Hello reloaded World"

(defroutes app-routes
  (GET "/" [] "Hello reloaded World")
  (route/not-found "Not Found"))

Now, refresh your browser and see the changes made.

Hint:: You should only need to restart the server again if you add libraries or define code outside of the scope of the app. Or if your code crashes the server, but I am sure that wont happen :)
