    static void Main(string[] args)
    {
        //Instantiate person object
        var person = new Person();
        //Give it a default name
        person.Name = "Andrew";

        //Register to the nameChangedEvent, and tell it what to do if the person's name changes
        person.nameChangedEvent += (sender, nameChangedArgs) =>
        {
            Console.WriteLine(nameChangedArgs.NewName);
        };

        //This will trigger the nameChanged event.
        person.Name = "NewAndrewName";

        Console.ReadKey();
