| AddNode(INode) | (Overrides BaseGraphAddNode(INode)) |

| FreeVisitedFlag |
Frees a visited flag.
This is a safe but O(n) operation, as it resets the visited flag in the graph.
(Overrides BaseGraphFreeVisitedFlag(Int32)) |

Attention! A marked element stays marked, so a later allocation hands out a dirty visited flag!
Use only if you can ensure that all elements of that flag are unmarked before calling.
