/**
  * This sketch demonstrates how to use the <code>effectCount</code> method of an <code>Effectable</code> class. 
  * The class used here is <code>AudioOutput</code>, but you can also get the effect count of <code>AudioInput</code>, 
  * <code>AudioPlayer</code>, and <code>AudioSample</code> objects. The effect count is simply how many effects 
  * are currently attached to the <code>Effectable</code>.
