PaymentMethod defines a way of paying in the shop. This factory method returns objects that implements this interface

func GetPaymentMethod

func GetPaymentMethod(m int) (PaymentMethod, error)

CreatePaymentMethod returns a pointer to a PaymentMethod object or an error if the method is not registered. We used "new" operator to return the pointer but we could also used &Type{} althought new makes it more readable for newcomers could be confusing
