Method to create an IntList from an argument list. You don't have to understand this code. We have it here because it's convenient with testing. It's used like this: IntList myList = IntList.of(1, 2, 3, 4, 5); will create an IntList 1 -> 2 -> 3 -> 4 -> 5 -> null. You can pass in any number o

(int... argList)
