    /* Todo:
        well .. strictly spoken this script is bogus. All data has to be assembled beforehand either by hand or by querying wowhead
        we would need this script to prevent this type-fest and do it propperly ourselves.. *dang*

        probably like this:

        virtualId = 0
        get itemsetIds ordered ascending
        foreach itemsetId
            lookup pieces
            sort pieces by slot
            if slots conflict
                group items by ItemLevel ordered ascending
                assign: first group => regularId
                assign: other groups => --virtualId
            end if
        end foreach

        this will probably screw the order of your set-pieces and will not result in the same virtualIds like wowhead, but
        they are years beyond our content anyway, so what gives...

        lets assume, you've done something like that, so ...

        ... onwards!
