Module Builder

module Builder: sig .. end

Graph builders in order to persistent/imperative graphs sharing a same signature.

module type S = sig .. end

module type INT = S  with type G.V.label = int

module P: functor (G : Sig.P) -> S  with module G = G

Persistent Graphs Builders.

module I: functor (G : Sig.I) -> S  with module G = G

Imperative Graphs Builders.
