[semidet]rdf_equal_graphs(+GraphA, +GraphB, -Substition)

True if GraphA and GraphB are the same under Substition. Substition is a list of BNodeA = BNodeB, where BNodeA is a blank node that appears in GraphA and BNodeB is a blank node that appears in GraphB.

`GraphA`	is a list of `rdf(S,P,O)` terms
`GraphB`	is a list of `rdf(S,P,O)` terms
`Substition`	is a list if NodeA = NodeB terms.

To be done: The current implementation is rather naive. After dealing with the subgraphs that contain no bnodes, it performs a fully non-deterministic substitution.
