Implement the simplified graph ADT described in Project P-13.1 using the adjacency list structure.

Data from in Project P-13.1

Write a class implementing a simplified graph ADT that has only functions relevant to undirected graphs and does not include update functions using the adjacency matrix structure. Your class should include a constructor that takes two collections (for example, sequences)—a collection V of vertex elements and a collection E of pairs of vertex elements—and produces the graph G that these two collections represent.
