Create a public class CountLinkedList that extends SimpleLinkedList, which has an zero-argument constructor. Provide an instance method count that accepts an Any as a parameter and returns how many times the object appears in the list as an Int. You can assume that the passed Any is not null, and that the list will not contain any null values.

As a reminder, our SimpleLinkedList is composed of a chain of Items, where Item is defined as an inner class on SimpleLinkedList:

The SimpleLinkedList class also has a start property that refers to the start of the list, or null if the list is empty. Note that the list that you are extending does not have a size field or a get method, meaning that you will need to walk the list to solve this problem. (That's the point!)
