>
> The motivation of this feature is to provide users a way to directly
> designate a dimension set to be prebuilt. It's an additional way to define
> prebuilt cuboids besides static rules and will only be feasible for an empty
> cube. If hot cuboids are imported during cube design phase and it is able to
> go through cube planner algorithm to get recommended cuboids, regardless
> whether the total number of defined cuboids is less than the threshold to
> trigger cube planner phase one, the cube planner phase one will be triggered
> and these imported cuboids will be regarded as mandatory cuboids for cube
> planner algorithm.
> Corresponding to the import feature, hot cuboids should be able to exported
> for future cube upgrading and so on.
