The idea is to sort a block of cells in one direction by swapping the

planes which are canonical to the sort key vectors. An example is to
|

sort a two dimensional block line-wise with one column as sort key.
|

You can have multiple sort keys which all have the same direction and

you can sort a cube plane-wise.
