Void endWin()
Usage
End curses windowing. This should always be called before the program exits, regardless of the cause of the exit.
Note that the Curses library changes the buffering of standard output, and so functions such as Prelude::putStr will not always work as expected. If you need to output further text after Curses windowing is ended but before the program finishes, and it is important that this text is immediately visible, then use IO::flush on stdout
