 * ControlP5 Bang
 * A bang triggers an event that can be received by a function named after the bang.
 * By default a bang is triggered when pressed, this can be changed to 'release' 
 * using theBang.setTriggerEvent(Bang.RELEASE).
 *
 * find a list of public methods available for the Bang Controller
