RunPattern demonstrates coordination among the AddressBook objects to reschedule an appointment. It creates
three AddressBooks , setting up conflict-ing appointments in two of them. Next, it instructs an AddressBook to
update the appointment. This results in an appointment in the address books with the first start time available to
all three AddressBooks : 12 noon.
