Implementing the window class

Now that we have our blueprint, let's begin actually building our window class. The entry and exit points seem as good a place as any to start with:

Window::Window(){ Setup("Window", sf::Vector2u(640,480)); }

Window::Window(const std::string& l_title, const sf::Vector2u& l_size)

Window::~Window(){ Destroy(); }

Both implementations of the constructor and destructor simply utilize the helper methods which we'll be implementing shortly. There's also a default constructor that takes no arguments and initializes some pre-set default values, which is not necessary, but it's convenient. With that said, let's take a look at the setup method:

void Window::Setup(const std::string l_title, const sf::Vector2u& ...
