@twalthr I looked around and realized that current `+` expression could
support TimeInterval (TimePoint) addition, thus the timestampAdd api is
duplicated and seems have no necessary.
so I only made these changes:
1. add `1.week` expression
2. modify `quarter` as `1.quarter`
3. modify Extract to support extracting QUARTER and WEEK, as suggested and
verified by @walterddr
Please have a review, @twalthr @fhueske @walterddr @hequn8128 thanks for
all of you,
