(** <b>Edges may be labeled or not</b>:
- Unlabeled: there is no label on edges
- Labeled: you have to provide a label implementation as a functor
parameter.
<b>Vertices may be concrete or abstract</b>:
- Concrete: type of vertex labels and type of vertices are identified.
- Abstract: type of vertices is abstract (in particular it is not equal
to type of vertex labels
<b>How to choose between concrete and abstract vertices for my graph
implementation</b>?
Usually, if you fall into one of the following cases, use abstract
vertices:
- you cannot provide efficient comparison/hash functions for vertices; or
- you wish to get two different vertices with the same label.
In other cases, it is certainly easier to use concrete vertices. *)

(** {2 Bidirectional graphs}
Bidirectional graphs use more memory space (at worse the double) that
standard concrete directional graphs. But accessing predecessors is in
O(1) amortized instead of O(max(|V|,|E|)) and removing a vertex is in
O(D*ln(D)) instead of O(|V|*ln(D)). D is the maximal degree of the
graph. *)

(** Faster implementations for abstract (un)labeled (di)graphs
when vertices are _not shared_ between different graphs.
This means that, when using the following implementations, two different
graphs (created with two calls to [create]) must have disjoint sets of
vertices. *)
