+/** 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);
