> now Hybrid uses every cube's latest segment to check whether overlap exists, but it can't cover all cases.
> example:
> hybrid:
>  cube1:
>  segment1: range(2012-01-01, 2012-01-02)
> cube2:
>  segment1: range(2012-01-01, 2012-01-02)
>  segment2: range(2012-01-03, 2012-01-04)
> this hybrid has overlap segment range(2012-01-01, 2012-01-02), but the program can not find out.
