/**
 * Provides a base decorator that enables additional functionality to be added
 * to a BidiMap via decoration.
 * <p>
 * Methods are forwarded directly to the decorated map.
 * </p>
 * <p>
 * This implementation does not perform any special processing with the map views.
 * Instead it simply returns the set/collection from the wrapped map. This may be
 * undesirable, for example if you are trying to write a validating implementation
 * it would provide a loophole around the validation.
 * But, you might want that loophole, so this class is kept simple.
 * </p>
 *
 * @param <K> the type of the keys in this map
 * @param <V> the type of the values in this map
 * @since 3.0
