Constructs a \Drupal\Core\Template\TwigReference object.
The argument to the constructor is ignored as it is not safe that this will always be a reference.
To set a reference use:
$obj = new TwigReference();
$obj
->setReference($variable);
$array: The array parameter is ignored and not passed to the parent
public function __construct($array = NULL) {
parent::__construct();
}
