Adding a bootstrapper in UWP

The bootstrapper for UWP is identical to the other platforms:

1. In the root of the UWP project, create a new class called Bootstrapper.cs.
2. Add the following code to it:

public class Bootstrapper : DoToo.Bootstrapper
{
    public static void Init()
    {
        var instance = new Bootstrapper();
    }
}

And as with the other platforms, we need to call the Init method in a good place:

1. In the UWP project, open up the App.xaml.cs file. 
2. Locate the call to the Xamarin.Forms.Forms.Init() method and add the code in bold:

Xamarin.Forms.Forms.Init(e);
Bootstrapper.Init();
