/**
  * This sketch demonstrates how to use the <code>hasControl</code> method of a <code>Controller</code> object. 
  * The class used here is an <code>AudioOutput</code> but you can also use test for controls of  
  * <code>AudioSample</code>, <code>AudioSnippet</code>, <code>AudioInput</code>, and <code>AudioPlayer</code> objects. 
  * <code>hasControl</code> takes one of the static control types of <code>Controller</code> as the argument. These are 
  * <code>Controller.BALANCE</code>, <code>Controller.GAIN</code>, <code>Controller.MUTE</code>, <code>Controller.PAN</code>, 
  * <code>Controller.SAMPLE_RATE</code>, and <code>Controller.VOLUME</code>. You should always check if a control 
  * is available before you attempt to use it.
