> For cube optimization, cuboids to be pre-calculated need to be adjusted.
> During this phase, there are three kinds of cuboids:
> # cuboids to be kept
> # cuboids to be removed
> # cuboids to be added
> The *cuboids to be added* can be derived from the base cuboid. Thus for
> cubing job, we introduce a new input , base cuboid formatted by sequence file
