TitanLabel is an extension of {@link TitanType} for edges.

In addition to {@link TitanType}, TitanLabel defines the directionality of edges:

Directed: An edge is directed if the order or position of its vertices matters. For directed edges, the outgoing vertex is considered the start and the incoming vertex the end. By default, labels and therefore edges are directed. Father is an example of a directed label.
Unidirected: An edge is unidirected if it is directed but only pointing in one direction. This means, the edge can only be traversed in the outgoing direction. As an example, a hyperlink is a unidirected edge. Unidirected edges can be stored more efficiently.
