      and the class VerboseMO:

      class VerboseMO extends Metaobject
      {
       public VerboseMO(Object base,Object args[])
       {
       super(base,args);
       System.out.println("Reflective Output: New instance of:"+base.getClass().getName()+"created");
       }
      
       public Object trapFieldRead(String name)
       {
      
       }
      
       public Object trapMethodcall(int id, Object[] args)
