Homework: Array Deep Copy

Created By: Geoffrey Challen

/ Version: 2020.10.0

Create a public class named Copier. Copier should provide a single static method named copy that accepts an array of Items. It should return a deep copy of the passed array: meaning that the returned array should contain references to new copies of the objects contained in the original array. Item provides a copy constructor that you can use to make copies. If the passed array is null, copy should return null.
