Singly Linked Lists

* Use class private and public

* Add numbers to the front (head)

* Add numbers to the last (tail)

Create a singly linked list which contains 3 nodes. The user is requested to provide a single value which will become the "elem" value for the node. Then repeat the process 2 more times. Each node is to be added at the end of the list. After you have completed the list, read thru the list from the beginning and print each node.
