Mark Baker 08673b5820 Initial experiments using the new Database query logic with Conditional Statistical Functions (#1880) ...

- Refactoring of the Statistical Conditional functions (`AVERAGEIF()`, `AVERAGEIFS()`, `COUNTIF()`, `COUNTIFS()`, `MAXIFS()` and `MINIFS()` to use the new Database functions codebase.
- Extended unit testing
- Fix handling for null values
- Fixes to wildcard text searches

There's still scope for further improvements to memory usage and performance; but for now the code is stable with all unit tests passing
