Function is_isomorphic

Source 
pub fn is_isomorphic<G0, G1>(g0: G0, g1: G1) -> bool
where
    G0: NodeCompactIndexable + EdgeCount + GetAdjacencyMatrix + GraphProp + IntoNeighborsDirected,
    G1: NodeCompactIndexable + EdgeCount + GetAdjacencyMatrix + GraphProp<EdgeType = G0::EdgeType> + IntoNeighborsDirected,
Expand description

[Generic] Return true if the graphs g0 and g1 are isomorphic.

Using the VF2 algorithm, only matching graph syntactically (graph structure).

The graphs should not be multigraphs.
