/**
 * <p>
 * Controller is an abstract class that is extended by any available controller within controlP5. this is the full
 * documentation list for all methods available for a controller. An event triggered by a controller will be forwarded
 * to the main program. If a void controlEvent(ControlEvent theEvent) {} method is available, this method will be
 * called.
 * </p>
 * <p>
 * A Controller can notify the main program in 2 different ways:
 * </p>
 * <ul>
 * <li>(1) add method controlEvent(ControlEvent theEvent) to your sketch. ControlP5 will automatically detect this
 * method and will used it to forward any controlEvent triggered by a controller - you can disable forwarding by using
 * setBroadcast(false) {@link controlP5.Controller#setBroadcast(boolean)}</li>
 * <li>(2) each controller requires a unique name when being create. In case an existing name is used for a newly
 * created Controller, the existing one will be overwritten. each unique name can be used to automatically link a
 * controller to either a method or a field within your program.</li>
 * </ul>
