+ * Simple, but all-in-one plugin implementation. Resembles look & feel of
+ * to MFC control-bars. Handles painting of pane and items in it.
+ * Fires bar/layout customization event, when user right-clicks bar/pane. 
+ * Hooking an instance of this and row-layouting plugins per each pane, 
+ * would be enough for the frame layout to function properly.
+ * (they are plugged in autimatically by wxFrameLayout class)
