yes, traversing the OBMol and putting it into the ARGraph takes some time, 
especially because one cannot use the OBAtom indexes while InsertNode 
emits it's _own_ node_id and that has to be stored in a lookup table to 
make the connection between OBAtom index and ARGraph index when inserting 
a bond.

Do you have a minimum working example of how to use your vf2 
implementation with RDKit molecules so I get an idea how it could be 
adapted to OMMol objects?

Best Regards
