/**
  * This sketch demonstrates how to use the cue method of AudioPlayer. 
  * When you cue, it is always measured from the beginning of the recording. 
  * So cue(100) will set the "playhead" at 100 milliseconds from the beginning 
  * no matter where it currently is. Cueing an AudioPlayer 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(). 
  *
  * Click in the window to cue to that position in the file.
