Finds the set of nodes reachable from a particular node, with a blacklist.
Finds the set of nodes reachable from a particular node, with a blacklist. The semantics of adding a node to the blacklist is that any of its inedges will be ignored in the traversal. The
root
node is *not* included in the returned set unless it is possible to reachroot
along a non-trivial path beginning atroot
