Useful UIView extensions for animating views - usually used when UIView is updated or interacted with

	extension UIView {

	func springIn(duration: TimeInterval = 0.5, delay: Double = 0, fromScale: CGFloat = 0.6) {
	self.layer.removeAllAnimations()
	self.alpha = 1
	self.transform = CGAffineTransform(scaleX: fromScale, y: fromScale)
	UIView.animate(withDuration: duration, delay: delay, usingSpringWithDamping: 0.5, initialSpringVelocity: 3.0, options: [.curveEaseInOut, .allowUserInteraction], animations: {
	self.transform = .identity
	})
	}
