TextUndoManager (Groovy 4.0.4)

groovy.console.ui.text.TextUndoManager

```
public class TextUndoManager
extends UndoManager
```
To use this, simply drop this as an UndoableEditListener into your document, and then create actions to call undo/redo as needed (checking can undo/redo first, of course).
