Take HIERARCHY queries to a HIGHER LEVEL

Nice one Connor. Like the GROUP BY clauses, there is a lot of functionality in Oracle SQL that has been available for quite a long time, but few seem to use it. Pity, as performance, and output are enhanced by digging into the manuals and finding what functionality is available.
