This node is called the +"midpoint node". +The path returned is the path src -> ... -> midpoint -> ... -> dst, +which is always a shortest path between src and dst. + +The graph direction of both BFS can be configured separately. By +default, the dst-BFS will use the graph in the opposite direction than +the src-BFS (if direction = FORWARD, by default direction_reverse = +BACKWARD, and vice-versa). The default behavior is thus to search for +a shortest path between two nodes in a given direction. However, one +can also specify FORWARD or BACKWARD for *both* the src-BFS and the +dst-BFS. This will search for a common descendant or a common ancestor +between the two sets, respectively.
