/**
* This is simply 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.
* Thus, this is simply a tag interface.
