/** The 7fold game is a simple number game.  7 slots (horizontally) are filled one
 * at a time with numbers 1 through 7.  If the number of digits vertically or horizontally
 * add up to the value of a digit in that row (that are touching) then those digits are removed.
 * 
 * This uses the serially controlled uOLEDs by 4D Systems.
 *
 * This is a private library written by Aaron Goselin.  While this may change in the future,
 * in the case of accidental posting to the internet in general, use of this library by an
 * individual or organization other than Aaron Goselin is prohibited.
 *
 * Example:
 * @code
 * // Draw text on the screen.
 * // Accessing from main()
 * #include "mbed.h"
 * #include "uOLED.h"
 * #include "uOLED_watch.h"
 * #include "games/7fold/7fold.h"
 * 
 * uOLED SGC(p9, p10, p11);
 * uOLED_watch watch(&SGC);
 * 7fold 7fold();
 *
 * int main()
 * {    
 *      // Draws 7fold main menu.
 *      monkey.draw7foldMainMenu();
