The module curses.panel defines the following functions:
Returns the bottom panel in the panel stack.
Returns a panel object, associating it with the given window win.
Be aware that you need to keep the returned panel object referenced
explicitly. If you don't, the panel object is garbage collected and
removed from the panel stack.
Returns the top panel in the panel stack.
Updates the virtual screen after changes in the panel stack. This does
not call curses.doupdate(), so you'll have to do this yourself.
