UIView extension

Init

    convenience init (x: CGFloat,
        y: CGFloat,
        w: CGFloat,
        h: CGFloat)

Frame

Quick access and manupliate to CGRect values of UIView's frame
    var x: CGFloat {
        get {
            return self.frame.origin.x
        } set (value) {
            self.frame = CGRect (x: value, y: self.y, width: self.w, height: self.h)
        }
    }
    var y: CGFloat {
        get {
            return self.frame.origin.y
        } set (value) {
            self.frame = CGRect (x: self.x, y: value, width: self.w, height: self.h)
