New schemas backup, other one did not restore properly.
Add slf4j logging facility.
Work in progress on rule implementation:
OneToAnyJoinRule works for explicit INNER JOIN clauses,
does not handle implicit inner joins.  So, for example this works:

SELECT e.name, s.name FROM employee e INNER JOIN employee s.ssn=e.manager_ssn;

But this does not:

SELECT e.name, s.name FROM employee e, employee s WHERE s.ssn=e.manager_ssn;
