 * Internally each bean is registered into {@link com.google.inject.multibindings.Multibinder}.
 * <p>To use {@link com.google.inject.multibindings.MapBinder} create your own annotation with single
 * attribute {@code value} and annotate it with {@code @Plugin}. New annotation value will be used as key.</p>
