Functions
---------
The module `curses.panel' defines the following functions:
`bottom_panel()'
Returns the bottom panel in the panel stack.
`new_panel(win)'
Returns a panel object, associating it with the given window WIN.
`top_panel()'
Returns the top panel in the panel stack.
`update_panels()'
Updates the virtual screen after changes in the panel stack. This
does not call `curses.doupdate()', so you'll have to do this
yourself.
