Dan Kortschak	46d85b5bdf	graph: avoid issues around graph node retrieval subtleties ... With the approach to graph node mutation on edge setting the previously existed there was an issue that the edge last used connect a pair of nodes could result in a difference in the nodes being returned by a node query compared to the same node associated with edges returned from an edge query. This change avoids dealing with that by making it implementation dependent and stating this, and by making all the node-storing graphs we provide mutate the nodes when edges are set.	2018-09-29 19:26:44 +09:30
