//! <h1>EV-LM3S811 Quickstart Application (qs_ev-lm3s811)</h1>
//!
//! A game in which a ship is navigated through an endless tunnel.  The
//! potentiometer is used to move the ship up and down, and the user push
//! button is used to fire a missile to destroy obstacles in the tunnel.  Score
//! accumulates for survival and for destroying obstacles.  The game lasts for
//! only one ship; the score is displayed on the virtual UART at 115,200, 8-N-1
//! during game play and will be displayed on the screen at the end of the
//! game.
//!
//! Since the OLED display on the evaluation board has burn-in characteristics
//! similar to a CRT, the application also contains a screen saver.  The screen
//! saver will only become active if two minutes have passed without the user
//! push button being pressed while waiting to start the game (i.e. it will
//! never come on during game play).  An implementation of the Game of Life is
//! run with a field of random data as the seed value.
//!
//! After two minutes of running the screen saver, the display will be turned
//! off and the user LED will blink.  Either mode of screen saver (Game of Life
//! or blank display) will be exited by pressing the user push button.  The
//! button will then need to be pressed again to start the game.
