C# Class GuiLabs.Undo.SimpleHistory

IActionHistory represents a recorded list of actions undertaken by user. This class implements a usual, linear action sequence. You can move back and forth changing the state of the respective document. When you move forward, you execute a respective action, when you move backward, you Undo it (UnExecute). Implemented through a double linked-list of SimpleHistoryNode objects. ====================================================================
