Wiring up events

Each time a new SwiperControl instance is created, we need to wire up the events, as follows:

1. Open MainPage.xaml.cs. 
2. Add the following code in bold to the InsertPhoto() method:

private void InsertPhoto()
{
    var photo = new SwiperControl();
    photo.OnDeny += Handle_OnDeny;
    photo.OnLike += Handle_OnLike;
 
    this.MainGrid.Children.Insert(0, photo);
} 

The added code wires up the event handlers that we defined earlier. The events make it really easy to interact with our new control. Try it for yourself and have a play around with the app that you have created.
