A simple address-book implementation.
This version includes some argument-validity checking.
How to start this project:
Either: Create an AddressBook object and add
contact details (such as name, address, and phone) to it.
Or: create an AddressBookDemo and call its showInterface method.
This will create a sample AddressBook along with a text
interface for the purposes of interactive experimentation.
