Attaching Handy Functionality

Since the ArrayList is all encapsulated in a class with methods attached to it, we have an excellent chance to build other convenient functionality on our lists beyond what's specified in the List ADT.

Exercise: Build Copy Function

Write a new method in the List class called copy that creates a new instance of an List and returns it filled with the contents of the original list.

The copy method will be useful if you ever need to copy a list and manipulate it without making changes to the original list.
