This is the proposed mapping for the employee/insurance bidirectional relationship.  Key features
of this mapping are:
 *The insurance table contains a foreign key to the persons table.
 *The MedicalInsurance and DentalInsurance reference fields of Employee are mapped-by the
employee field of Insurance.
