Example:

    people[0] = Person(3, "Bob");
    people[1] = Person(4, "Joe");
    people[2] = Person(5, "Sue");

Example 2:

	people.insert(std::pair <int, Person> (0, Person(3, "Bob")));
	people.insert(std::pair <int, Person> (1, Person(4, "Joe")));
	people.insert(std::pair <int, Person> (2, Person(5, "Sue")));
