Updating statistics

At the beginning of the chapter, we added some controls to the XAML that displayed the number of planes and boxes that were present in the game. It's now time to add some code to update those numbers. We will be using internal messaging to decouple the game from the Xamarin.Forms page that we use to display this information.

The game will send a message to the main page that will contain a class with all the information we need. The main page will receive this message and update the labels.
