Creates a new graph with nodes mapped by fNode and with an untouched edge structure otherwise.
You can call this flavor only if this graph's edge type is generic. Otherwise see mapBound.
If this graph also contains typed edges, the typed edge's partial map function will be called to replace the ends. If the partial function is not defined, there will be an attempt to fall back to a generic edge. If that attempt also fails the edge will be dropped. So, if you have a mixed graph with generic and typed edges, prefer mapping edges directly to avoid leaving edges out.
