What is this?

This is intended as a gentle introduction to TDD/BDD for people who have not experienced it before. The idea is to implement a simple Undo/Redo stack as can be found in any text editor. We all know how those work, so you can focus on letting the tests drive the implementation. This should be a fairly short exercise.

You could start by using your TDD'ed implementation from here. Do that exercise first if you haven't already.
