Hi,

So I'm working on creating a visualization for a data structure in Java. I already have the implementation of the data structure (Binary Search Tree) to start with, but I need to add some additional functionality to the included node class. As far as conventions and best practices are concerned, should I create a subclass of the node with this added functionality or should I just modify what I have and document it there?

My question is similar to what's asked here but that's a little over my head.

I know it probably doesn't matter much for what I'm doing, so I'm asking this more as a general thing.
