Sorts the component designated by the given node topologically.
Sorts the component designated by the given node topologically. Only nodes connected with this node will be included in the resulting topological order. If the graph is known to be connected choose GraphTraversal#topologicalSort instead. $SEEFLUENT

include successors of root. withSubgraph restricts the successor nodes to
be included but not predecessors that will be excluded in total.
