Change dispatchEvent method signature to use varargs
----------------------------------------------------

         Key: BEEHIVE-893
         URL: http://issues.apache.org/jira/browse/BEEHIVE-893
     Project: Beehive
        Type: Improvement
  Components: Controls  
    Versions: TBD    
 Environment: N/A
    Reporter: Xibin Zeng
    Priority: Minor


I suggest we use varargs in the org.apache.beehive.controls.api.events.EventDispatcher interface. This would make client code that use the method easier to read and easier to contrstuct. The fowllowing is the detail of this suggestion:

Before:

public Object dispatchEvent(ControlHandle target, EventRef event, Object [] args)
                  throws IllegalAccessException, IllegalArgumentException, 
                         InvocationTargetException;

After

public Object dispatchEvent(ControlHandle target, EventRef event, Object... args)
                  throws IllegalAccessException, IllegalArgumentException, 
                         InvocationTargetException;

For example, to dispatch a no-arg event,  the client code that calls this method would be

dispatcher.dispatchEvent(target, event);

Rather than

dispatcher.dispatchEvent(target, event, new Object[] {});

Similarily, it looks nicer when you have arguments.

Thanks
