  +/** 
  + * <code>MultiHashMap</code> is the default implementation of the 
  + * {@link MultiMap} interface. A <code>MultiMap</code> is a Map
  + * with slightly different semantics.
  + * Instead of returning an Object, it returns a Collection.
  + * So for example, you can put( key, new Integer(1) ); 
  + * and then a Object get( key ); will return you a Collection 
  + * instead of an Integer.
