code: public static <E1,E2> Collection<E2> mapColl(Iterable<E1> coll, Map<E1,E2> map, Collection<E2> newColl) {
  	return mapColl(coll, map2fun(map), newColl);
      }
docs: Similar to teh other <code>mapColl</code> method, but the
  function is given as a map.  This map is expected to map all
  elements from the entry collection <code>coll</code>.
