/**
  * This sketch demonstrates how to use the <code>loop</code> method of a <code>Playable</code> class. 
  * The class used here is <code>AudioPlayer</code>, but you can also loop an <code>AudioSnippet</code>.
  * When you call <code>loop()</code> it will make the <code>Playable</code> playback in an infinite loop.
  * If you want to make it stop looping you can call <code>play()</code> and it will finish the current loop 
  * and then stop. Press 'l' to start the player looping.
