you have to keep a history
stack of the recent operations performed by your app.
When someone pushes the "Undo" button, your app has to figure out
what the most recent operation was, and how to restore the state of
the app to that which just preceded that operation.
It really depends on what your app is doing, whether that works out
to be simple and easy, or really difficult.
