Description

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.
