`AddressBookParser` should not be in the Logic diagram

[QQH0828]

There is no link between AddressBookParser and the rest of the part in the Logic diagram. I feel that the AddressBookParser should not be in the diagram, since there is already an existing PetPalParser and AddressBookParser does not match the project itself.
