/******************************************************************************
*
*   A song is defined by a table of notes. The first byte sets the tempo. A 
*   high byte will give a low tempo, and opposite. Each tone consists of two 
*   bytes. The first gives the length of the tone, the other gives the frequency. 
*   The frequencies for each tone are defined in the "sound.h". Timer0 controls 
*   the tempo and the length of each tone, while Timer1 with PWM gives the 
*   frequency. The second last byte is a "0" which indicates the end, and the
*   very last byte makes the song loop if it's "1", and not loop if it's "0".
