* added DateField to changelog
* fixed conflict
* use INDEXED instead of INT_INDEXED for date fields
* Split Collector into an overall Collector and a per-segment SegmentCollector. Precursor to cross-segment parallelism, and as a side benefit cleans up any per-segment fields from being Option<T> to just T.
