LinkedListOfData

```
public class LinkedListOfData
extends java.lang.Object

A new Node is created for each Data object that is stored in the Linked-List. Each Node contains a reference to the Data object, and to the next Node in the Linked-List. Also, note that it should be possible for the user to insert 'null' values into a LinkedListOfData.
