/**
 * Annotates methods of a {@link Module} to add items to a {@link MapBinder}. The method's return
 * type, binding annotation and additional key annotation determines what Map this will contribute
 * to. For example,
 *
 *  * {@literal @}ProvidesIntoMap
 * {@literal @}StringMapKey("Foo")
 * {@literal @}Named("plugins")
 * Plugin provideFooUrl(FooManager fm) { return fm.getPlugin(); }
 *
 * {@literal @}ProvidesIntoMap
 * {@literal @}StringMapKey("Bar")
 * {@literal @}Named("plugins")
 * Plugin provideBarUrl(BarManager bm) { return bm.getPlugin(); }
 * 
 *
 * will add two items to the {@code @Named("plugins") Map} map. The key 'Foo' will
 * map to the provideFooUrl method, and the key 'Bar' will map to the provideBarUrl method. The
 * values are bound as providers and will be evaluated at injection time.
 *
 * Because the key is specified as an annotation, only Strings, Classes, enums, primitive types
 * and annotation instances are supported as keys.
