/**
 * Annotates methods of a {@link Module} to add items to a {@link Multibinder}. The method's return
 * type and binding annotation determines what Set this will contribute to. For example,
 *
 *  * {@literal @}ProvidesIntoSet
 * {@literal @}Named("urls")
 * String provideFooUrl(FooManager fm) { returm fm.getUrl(); }
 *
 * {@literal @}ProvidesIntoSet
 * {@literal @}Named("urls")
 * String provideBarUrl(BarManager bm) { return bm.getUrl(); }
 * 
 *
 * will add two items to the {@code @Named("urls") Set} set. The items are bound as
 * providers and will be evaluated at injection time.
