val find : key -> 'a t -> 'a

find k t returns the element associated with the key k in t. Raises Table.TABLE.Not_found if no such element exists

val fold : ( key -> 'a -> 'b -> 'b ) -> 'b -> 'a t -> 'b

fold f a t returns f kn vn (f kn-1 vn-1 (...(f k1 v1 a) ...)) where the ki and vi are the associated values in t. The elements are listed in order wrt. to the key
