SpriteKit Touch Visualizer ==========================  Custom objective-c classes for visualizing each finger during touch input in SpriteKit apps.   Useful for:  1. When you are building a binary to be used especially for screen-capturing an app preview movie to be displayed in the iTunes AppStore (as described here:  https://developer.apple.com/app-store/app-previews/),   2. Game tutorials or other in-app guidance, to theach the user how to use your app.   See the attached sample project to see how to use the classes in your own game. In short, you should modify your view controller code so that it loads a view of the type `TouchVisualizerView` (subclass of `SKView`). This basically boils down to implementing/overriding the `UIViewController` instance method `-loadView`.
