+ * This is intended as a "quick functionality test" of the
+ * Spark-X Alphanumeric Displays (SparkFun SPX-16391, SPX-16425,
+ * SPX-16426, and SPX-16427).
+ * 
+ * The sketch will illuminate one segment on each digit, with
+ * each digit showing a different segment, cycling through all
+ * 14 segments twice, then illuminating the colon and then the
+ * decimal, before pausing briefly with a blank display then
+ * repeating the process.
+ * 
+ * By the way, the reason for having the four digits "out of
+ * step", so to speak, is that it proves that each is being
+ * independantly addressed.
+ * 
+ * Note that as it stands, it is intended to test only one
+ * display unit at a time, with the default address on the
+ * unit.  However, it can easily be expanded to relax these
+ * restrictions, and can also be modified for use as a
+ * "power-on self test" at the beginning of a more complex
+ * sketch.
