An IdentifierGenerator that returns a Long, constructed using
a hi/lo algorithm. The hi value MUST be fetched in a seperate transaction
to the Session transaction so the generator must be able to obtain
a new connection and commit it. Hence this implementation may not
be used when Hibernate is fetching connections from an application
server datasource or when the user is supplying connections. In these
cases a SequenceHiLoGenerator would be a better choice (where
supported).
