<DL>
<DD>Sets alive to false. Note that this is a one way operation:
 dead edits cannot be resurrected.  Sending undo() or redo() to
 a dead edit results in an exception being thrown.

 Typically an edit is killed when it is consolidated by another
 edit's addEdit() or replaceEdit() method, or when it is
 dequeued from an UndoManager<DD><DL>
