Combining inheritance and protocols

folder:
open class AngryCatAlien : AngryCat, Alien { open var numberOfEyes: Int = 0 init (nickName: String, age: UInt, fullName: String, initialScore: UInt, x: UInt, y: UInt, numberOfEyes: Int) { super.init(nickName: nickName, age: age, fullName: fullName, initialScore: initialScore, x: x, y: y) self.numberOfEyes ...
