The SmartUndoButton can be added to a Category item on the Ribbon or to an ItemsGroup.
It  implements the functionality of a menu button with popup menu. It is possible to select a couple of actions from this list and execute ("undo" or "redo") all of them. If the button itself is clicked, then only one (last added) action should be executed. In fact, the button acts as LIFO stack.
When we select any item from the popup menu, the action located after selected item will be removed from the LIFO Stack.
The SmartUndoButton can be of two types. If the value of the property CustomUndoButton is set to true, names of actions will be displayed in popup menu, other wise the number of action to be undone will be show as a text on every button. The size of the SmartUndoButton stack is non fixed.  Its size depends on the number of action to undo (or redo).
