> 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.
