Léo Ercolanelli	0d6094a3ea	sumMap: return types less prone to oveflows ... It used to be that sumMap would return the same type as the values columns. If columns of Array(UInt8) were to be given, that would really easily cause oveflow. It now uses `getWidenDataType` (and ultimately `NearestFieldType`) in order to define the result type.	2019-01-25 14:29:45 +01:00
