.sp
Functor building an implementation of the hashtable structure\&.
The functor 
.B Hashtbl\&.MakeSeeded
returns a structure containing
a type 
.B key
of keys and a type 
.B \&'a t
of hash tables
associating data of type 
.B \&'a
to keys of type 
.B key
\&.
The operations perform similarly to those of the generic
interface, but use the seeded hashing and equality functions
specified in the functor argument 
.B H
instead of generic
equality and hashing\&.  The 
.B create
operation of the
result structure supports the 
.B ~random
optional parameter
and returns randomized hash tables if 
.B ~random:true
is passed
or if randomization is globally on (see 
.B Hashtbl\&.randomize
)\&.
