Now that we've created our MapView, learned how to add pins (annotations), and learned how to customize our annotations too, we can integrate this straight into our recipe app.
In this section, we'll hook up our actual recipes to our MapView, placing an annotation on each country with a recipe. Then we'll use a custom annotation to list the country name and the number of recipes we have for that country.
We'll then take a look at the call out accessory view and how we can add a button that we'll be able to use to filter our ContentView list based on the country selected.
Finally, we'll add another navigation bar button item in order to clear our filter.
