            Person person = new Person("Founder & CEO", "Tobie", "Morgan Hitchcock", true);
            // Insert a record
            List<Person> tobie = driver.create(Person.class, "person", person);
            // Read records
            Iterator<Person> people = driver.select(Person.class, "person");
            // Print them out
            System.out.println("Tobie = " + tobie);
            System.out.println("people = " + people.next());
