/* Mamy sklep. W sklepie sprzedawane są różne towary. Te towary mają nazwę,

 * W sklepie towary kupują klienci. Klient to imię, nazwisko, adres. Klient może
 * kupować wiele towarów. Klient może kupować wiele towarów. Zakup kończy się 
 * wystawieniem faktury (adres klienta, sklepu, wykaz pozycji z kosztem, koszt całkowity)
 * z dodawaniem i usuwaniem pozycji z faktury. Aplikacja 
 * powinna umożliwiać gromadzenie informacji o fakturach (dodawanie, usuwanie 
 * pozycji), sprzedawcach, towarach.  */
