Graphs and Components
Graph a graph object
Edges, Vertices list of edges and vertices in a graph
M, V number of edges and vertices in a graph
Graph Representations
ToOrderedPairs get a list of edges
ToAdjacencyLists represent a graph as adjacency lists
ToAdjacencyMatrix represent a graph as an adjacency matrix
    
SymmetricQ test if a square matrix represents a symmetric relation
EquivalenceRelationQ test if a matrix defines an equivalence relation
