All white space changes. Moved hardware versions to header file. 

I corrected all the /* style comments to // comments to fit with
SparkFun style guides. Now works using the Arduino auto-format function.

Simon Says is a memory game. Start the game by pressing one of the four buttons. When a button lights up,
press the button, repeating the sequence. The sequence will get longer and longer. The game is won after
13 rounds.
This code is public domain but you buy me a beer if you use this and we meet someday (Beerware license).
Simon Says game originally written in C for the PIC16F88.

Simon tones from Wikipedia

- a (green, upper right, an octave higher than A) - 880Hz - 1.136ms,
0.568ms pulse
0.568ms pulse
- D (blue, lower left, a perfect fourth higher than the upper left)
587.33Hz - 1.702ms - 0.851ms pulse
587.33Hz - 1.702ms - 0.851ms pulse

784Hz - 1.276ms - 0.638ms pulse
The tones are close, but probably off a bit, but they sound all right.
The old version of SparkFun simon used an ATmega8. An ATmega8 ships
with a default internal 1MHz oscillator. You will need to set the
internal fuses to operate at the correct external 16MHz oscillator.
@ -39,148 +39,16 @@
The current version of Simon uses the ATmega328. The external osciallator
was removed to reduce component count. This version of simon relies on the
internal default 1MHz osciallator. Do not set the external fuses.
