Functor building an implementation of the hashtable structure\&.
The functor 
.ft B
Hashtbl\&.Make
.ft R
returns a structure containing
a type 
.ft B
key
.ft R
of keys and a type 
.ft B
\&'a t
.ft R
of hash tables
associating data of type 
.ft B
\&'a
.ft R
to keys of type 
.ft B
key
.ft R
\&.
The operations perform similarly to those of the generic
interface, but use the hashing and equality functions
specified in the functor argument 
.ft B
H
.ft R
instead of generic
equality and hashing\&.  Since the hash function is not seeded,
the 
.ft B
create
.ft R
operation of the result structure always returns
non\-randomized hash tables\&.
