Persistent hash table library using dbm under the carpet.

Thin layer on top of the dbm library (in opam) to provide modules providing a subset of the functionalities of the stdlib's Hashtbl module.

The four modules provided and their find functions are:

val Phashtbl.GenKeyToGenVal.find: ('a, 'b) t -> 'a -> 'b val Phashtbl.StrKeyToGenVal.find: 'b t -> string -> 'b val Phashtbl.GenKeyToStrVal.find: 'a t -> 'a -> string val Phashtbl.StrKeyToStrVal.find: t -> string -> string

The stdlib's Marshal module is used for serialization/deserialization to/from strings.
