/*
This library was intended to be a simple and user friendly wav audio player using standard
Arduino libraries, playing bare-bones standard format WAV files.
Many of the extra features have been added due to user request, and are enabled
optionally only to preserve the out of the box simplicity and performance initially
intended.

With MODE2 on, stereo tracks will be played using 4 pins, for 2 speakers in complimentary mode
In MULTI dual track mode, MODE2 will use a second timer for the second track.
