Gian Merlino d3a3b7ba0c Add virtual column types, holder serde, and safety features. (#3823) ... * Add virtual column types, holder serde, and safety features. Virtual columns: - add long, float, dimension selectors - put cache IDs in VirtualColumnCacheHelper - adjust serde so VirtualColumns can be the holder object for Jackson - add fail-fast validation for cycle detection and duplicates - add expression virtual column in core Storage adapters: - move virtual column hooks before checking base columns, to prevent surprises when a new base column is added that happens to have the same name as a virtual column. * Fix ExtractionDimensionSpecs with virtual dimensions. * Fix unused imports. * CR comments * Merge one more time, with feeling.		2017-01-26 18:15:51 -08:00
