/** ControllerUpdater
 *  Updates each registered controller when a certain event occurs. All output
 *  devices (MIDI controllers, GUI, OSC-UI's etc) are registered in order to
 *  stay up-to-date.
 * 
 *  This class does no scheduling, it passes the events to the Controllers
 *  immidiatly.
 * 
 *  The Logic class is the opposite of this: it takes input and Luppp processes
 *  it, pushing the relevant updates in state through ControllerUpdater to each
 *  registered device.
