/**
  * This sketch demonstrates how to use the <code>pause</code> method of a <code>Playable</code> class. 
  * The class used here is <code>AudioPlayer</code>, but you can also pause an <code>AudioSnippet</code>.
  * Pausing a <code>Playable</code> causes it to cease playback but not change position, so that when you 
  * resume playback it will start from where you last paused it. Press 'p' to pause the player.
