/**
  * This sketch demonstrates how to use the <code>cue</code> method of a <code>Playable</code> class. 
  * The class used here is <code>AudioPlayer</code>, but you can also cue an <code>AudioSnippet</code>.
  * When you cue, it is always measured from the beginning of the recording. So <code>cue(100)</code> will 
  * set the "playhead" at 100 milliseconds from the beginning no matter where it currently is. 
  * Cueing a <code>Playable</code> object will not change the playstate, meaning that if it was already playing 
  * it will continue playing from the cue point, but if it was not playing, cueing will not start playback, it 
  * will simply set the point at which playback will begin. If an error occurs while trying to cue, 
  * the position will not change. If you try to cue to a negative position or try to cue past the end of the 
  * recording, the amount will be clamped to zero or length(). 
  * <p>
  * Press 'c' to cue to 5000 milliseconds.
