These beans are derived from the O'Reilly example on CMP2.0.
The first purpose is to test the "cascade delete" facility.
They use the "automatic PK" facility too.

Application architecture :
--------------------------
Customer	1 <> 1	Address
			1  > 1	CreditCard
			1  > N	Phone
			1 <> N	Car			1 <> 1	Insurance
								1 <> N	Invoice

All beans are entity beans with CMP2 persistance.
