A simple view to animate in and out a blurry overlay. Use .blurIn() and .blurOut() to animate the blur. User interaction is passed through when the view is not blurry. NOTE: If you use storyboards, you need to drag out a UIVisualEffectView and set the class. It doesn't work if you drag out a plain old UIView.
