    //3a. You can either use the static func TipView.show like described below:
    PRGTipView.show(fromViewController: self, withConfiguration: config, completion: nil)
    
    //3b. Or you can create a PRGTipView instance and present it (it's a ViewController subclass)
    let tipView = PRGTipView(configuration: config)
