 * Diese Klasse stellt ein Event dar, welches über
 * den Event Controller verwaltet wird. Im Event wird
 * der Handler gespeichert, der beim Aufruf eines 
 * Events in einem JavaScript genutzt wird. Desweiteren
 * hat die Event Klasse die Möglichkeit, sich selbst 
 * zu rendern, d.h. es gibt den Code-Snippet zurück,
 * der für den Aufruf des Events notwendig ist.
