/**
* A graph is a collection of vertices, together with edges connecting
* some of the vertices.
*
* Implement a Graph class with the following properties:
* - There is only one public default constructor that produces an
* empty graph with no vertices (or edges).
* - operator+= is used to add a vertex with a given ID to the graph.
* if a vertex already has the given ID, a logic_error exception
* should be thrown.
* - hasEdge(int ID1, int ID2) returns true iff an edge between vertices
* with ids ID1 and ID2 exists.
* - addEdge(int ID1, int ID2) adds an edge between vertices with
* ids ID1 and ID2, respectively.
* if one of the IDs does not exist, or the edge already exists,
* an invalid_argument exception should be thrown.
* - operator[](int ii) returns the ii-th vertex in the graph (0-indexed)
* - numVertices() returns the number of vertices in the graph
* - numEdges() returns the number of edges in the graph
*
* @example
* Graph G;
* G+=3;
* G+=5;
* G+=3; // throws logic_error
* G.hasEdge(3,5); // returns false
* G.addEdge(5,3); // adds an edge connecting vertex 5 and 3.
* G.hasEdge(3,5); // returns true (edge between 5 to 3 == between 3 and 5).
* G[0]; // returns 3
* G.numVertices(); // returns 2 - vertex ID 3 and ID 5
* G.numEdges(); // returns 1 - between vertex ID 3 and ID 5

* Complete the class definitions and implementations, including constructors,
* destructors, setters, getters, and an external override of stream operator<< and operator>>
* to input and output each object.

* When overloading the ostream operators, the output should be formatted such that it includes all fields of the object.
* @example
* labFour_pZero_Person James("James");
* Jim.setBirthday("2010-02-28");
* cout << James; // outputs "James, 2010-02-28"
*
* When overloading the instream operators, the input should be formatted such that it includes all fields of the object.
* @example
* labFour_pZero_Person James;
* std::stringstream input("James, 2010-02-28");
* input >> James; // inputs "James, 2010-02-28"
*
* @example
