exclude registration from laravel auth code example

Example: exclude registration from laravel auth

Laravel 5.7 introduced the following functionality:
	Auth::routes(['register' => false]);

The currently possible options here are:
  Auth::routes([
    'register' => false, // Registration Routes...
    'reset' => false, // Password Reset Routes...
    'verify' => false, // Email Verification Routes...
  ]);

For older Laravel versions just override showRegistrationForm() and 
register() methods in

AuthController for Laravel 5.0 - 5.4
Auth/RegisterController.php for Laravel 5.5

public function showRegistrationForm()
{
    return redirect('login');
}

public function register()
{

}
