Initial Description
U ovoj biblioteci su definirane funkcije za izvršavanje operacija nad ATP listom: iniciranje prazne liste(InitL), funkcije koje vraćaju pozicije prvog i zadnjeg elementa(FirstL i EndL), funkcija za umetanje elementa(InsertL), funkcija koja vraća vrijednost elementa na nekoj poziciji(RetrieveL) te funkcije za brisanje pojedinog elementa(DeleteL) ili cijele liste(DeleteAllL).
