The whole homework is about implementation, not about extension.
Interfaces are abstract classes, hence they need to be implemented by
non abstract classes. Once they are implemented, you may use their
implementation as any other classes.
In the homework, you have two kinds of implementation: direct ones,
which you implement directly in Person class, and indirect one, such
as AddressInterface, which is implemented by AddressImpl class.
