sortSlotsfunction

The slots of a layout, as their numbers, put in order by the keys: ["z", "y", "x"] is layer by layer, row by row, across (the layout's own order), ["x"] lines them up from the left, ["-z"] has the top of the stacks first. Slots equal in every key keep their own order, and a key left out is settled last, in the order x, y, z, so the result is the same whatever the keys.
