UndoableEditReceiver (jump-b3p 6.0 API)

java.lang.Object
- org.locationtech.jts.jump.workbench.model.UndoableEditReceiver

```
public class UndoableEditReceiver
extends Object
```
Receives UndoableEdits from PlugIns and CursorTools. Also provides access to a Task's UndoManager.
In the documentation, the "receiving phase" refers to the time between the calls to #start and #stop.
If there is an exception that leaves this UndoableCommand execution partially complete and non-unexecutable, be sure to call #reportIrreversibleChange()
