ConcreteLabeled.E
Edges have type E.t and are labeled with type E.label. src (resp. dst) returns the origin (resp. the destination) of a given edge.

Edges are ORDERED_TYPE.
ORDERED_TYPE
type t = V.t * E.t * V.t
val compare : t -> t -> int
Edges are directed.
type vertex = vertex
val src : t -> vertex
Edge origin.
val dst : t -> vertex
Edge destination.
Edges are labeled.
type label = E.t
val create : vertex -> label -> vertex -> t
create v1 l v2 creates an edge from v1 to v2 with label l

val label : t -> label
Get the label of an edge.
