Type hints for setter assemblers

[janvernieuwe]

At the moment the setters have no type hints:

    /**
     * @param CardOrder $OrderInformation
     */
    public function setOrderInformation($OrderInformation)
    {
        $this->OrderInformation = $OrderInformation;
    }

It would be nice to enforce the types in the setters like so.

    /**
     * @param CardOrder $OrderInformation
     */
    public function setOrderInformation(CardOrder $OrderInformation)
    {
        $this->OrderInformation = $OrderInformation;
    }
