final class ViewController: UIViewController {

    enum SliderType: Int {
        case Count = 101
        case MaxRadius = 102

        case Interval = 104
        case MaxAlpha = 105
    }
    
    enum SegmentType: Int {
        case Orientation = 201
        case Color = 202
    }
    
    @IBOutlet weak var layerView: UIView!
    
    var pulseLayer: WWPulseLayer!

        pulseLayer = WWPulseLayer()
        
        pulseLayer.frame = CGRect(origin: layerView.center, size: .zero)
