ShortestPath

ShortestPath finds one shortest path between two nodes over a relation, counting steps:

var path = db.Query<IAttendee>()
             .ShortestPath(a => a.Friends, fromNodeId: aliceId, toNodeId: zaraId, maxLevel: 6)
             .Execute();

if (path.Found)
    Console.WriteLine($"{path.Length} steps: " + string.Join(" → ", path.Nodes.Select(a => a.FullName)));

Nodes and NodeIds run from the first node to the last, both included.
