Additionals adds

val add_to_list : key -> 'a -> 'a list t -> 'a list t

add k v m is m with k mapping to l such that l is v :: find k m if k was bound in m and [v] otherwise.

val add_to_set : (module Stdlib.Set.S with type elt = 'a and type t = 'set) -> key -> 'a -> 'set t -> 'set t

add (module S) k v m is m with k mapping to s such that s is S.add v (find k m) if k was bound in m and S.singleton [v] otherwise.
