11714,"[subgraph.hpp] add_vertex(u_global, g) on a subgraph does not recursively add to parent subgraphs",s.hammer@…,Jeremiah Willcock,"Hello,

One of the invariants of an induced subgraph is:
   - If vertex u is in subgraph g, then u must be in g.parent().

This is true if you call add_vertex(g) on a subgraph to create a new vertex.
If you however choose to add a already existing global vertex to the subgraph, this addition is not propagated to the parents of this subgraph.

I assume this is a bug and fixed it. The patch is on github:
https://github.com/j-4/graph/tree/fix-add_vertex-subgraph

I also created a pull request!
Thanks,
Stefan
