A very simple Hibernate configuration mapping the PERSON table to the Person class and
the ADDRESS table to the Address class. There is a one-to-many relationship between the PERSON and ADDRESS table.
The set element in the Person mapping creates the relationship from the PERSON to
the ADDRESS table and stores the Address instances in a java.util.Set.
The key element inside the set element indicates ADDRESS.PERSON_ID is
the column to match against PERSON.ID to retrieve addresses associated with a person.
