Graph operation traits

These traits are implemented for various graph representations built from standard library containers.

• ops::AddEdge adds an edge to an unweighted graph.
• ops::AddWeightedEdge adds an edge to a weighted graph.
• ops::CountAllEdges counts all edges in a graph.
• ops::CountAllVertices counts all vertices in a graph.
• ops::EdgeWeight gets the weight of an edge.
• ops::Indegree returns the indegree of a vertex.
• ops::IsEdge returns whether an edge exists between two vertices.
• ops::IterAllEdges iterates over all unweighted edges in a graph.
• ops::IterAllWeightedEdges iterates over all weighted edges in a graph.
• ops::IterEdges iterates over all unweighted edges of a source vertex.
• ops::IterVertices iterates over all vertices in a graph.
• ops::IterWeightedEdges iterates over all weighted edges of a source vertex.
• ops::Outdegree returns the outdegree of a vertex.
• ops::RemoveEdge removes an edge from a graph.
• ops::VertexWeight returns the weight of a vertex.
