Iteration 0 - Node Basics

Our Linked List will ultimately be composed of individual nodes, so in this iteration we’ll start with building out these nodes. Note that they are quite simple – a Node simply needs to have a slot for some data and a slot for a “next node”. Eventually this next_node position will be what we use to link the multiple nodes together to form the list.

For this iteration, build a simple node class that can perform these functions:

> require "./lib/node"
> node = Node.new("plop")
> node.data
=> "plop"
> node.next_node
=> nil
