== Overview ==
The PRO_LIB change manager tracks undo/redo changes made to properties.  

The goal of this task is to provide an end user interface to the change manager.  Add a user interface via the Edit menu for Undo and Redo.  I don't think we should expose skipping, as that would be confusing to the user.

== Task requirements ==

 * Add  menu items to the edit menu that tracks the state of the change manager
  * Undo works down the stack
  * Redo works up the stack
 * Add key commands (control-z, control-shift-z for redo) to the menu items
 * Disable the menu items if you are at the proper end of the stack

== Task result ==

The result of this task is code

== Implementation idea ==
 * Look at:
   * org.sophie2.core.prolib.util.UndoManager
   * org.sophie2.core.prolib.events.ProChange
 * See the related tasks for the APIs to talk to
