/**
  * This sketch demonstrates how to use the <code>rewind</code> method of a <code>Playable</code> class. 
  * The class used here is <code>AudioPlayer</code>, but you can also rewind an <code>AudioSnippet</code>.
  * Rewinding a <code>Playable</code> sets the position to zero, the beginning. Rewinding doesn't change 
  * the play state of a <code>Playable</code> so if it is playing or looping when you rewind, it will 
  * continue to play or loop after you rewind it. Press 'r' to rewind the player.
