        Write a program that prints out addresses for people and companies. 

        You can use the sample Person, Company, and Address classes from the lesson. 

        Create several instances of Person and Company, and add them to collections. 

        Loop through these collections, printing out the address for each company or person, like so:

            Jane Doe

            123 Main Street

            Sometown, OH, 12345

            United States

            Acme, Inc.

            123 Main Street

            Sometown, OH, 12345
