static <T> Set<T>	asSet(Iterable<T> c)	If the argument is already an instance of a set then cast it to a set and return it; otherwise create a new LinkedHashSet initialized with the given items
static <K,V> Set<V>	mapSet(Set<K> set, Map<K,V> map)	Short hand for Set result = source.stream().map(fn).collect(Collectors.toSet()) Maps a set of keys to a corresponding set of values via a given map TODO Probably this method can be replaced by something from guava
