Detailed Description

This class is used to describe horizontal references between graph nodes.

For example, if node B is a successor of node A (so that node A is a predecessor of node B), then two arcs are created: one to reference B in the successors of A, and one to reference A in the predecessors of B. When node B is both a predecessor and a successor of node A, four arcs are thus created. The graph can thus be seen as a directed half-edge data structure.
