Detailed Description

Implementation of undo functions.

The undo system requires calling startUndo() when starting a GUI command and calling endUndo() when ending the command. All changes to a score in response to a GUI command must be undoable/redoable by executing a sequence of low-level undo operations. This sequence is built by the code handling the command, by calling one or more undoOp()'s between startUndo() and endUndo().
