code: public Hoarde<T> each(Consumer<T> tocall) {
          for (int i = 0; i < actors.length; i++) {
              tocall.accept( (T) actors[i] );
          }
          return this;
      }
docs: iterate over each actor and execute tocall. E.g. hoarde.each( actor -> actor.init() )
  @param tocall
  @return
