* Change Additional Statistical Tests to Use Spreadsheet Context
With an earlier change, I made all but 18 Statistical tests run in spreadsheet context. This PR changes 12 of those 18. The remaining 6 usually return array results, so it is a tougher task to handle them. I will continue to think on it.
AVERAGEIF, AVERAGEIFS, and COUNTBLANK are changed to throw an Exception when a range is specified as a literal. They previously accepted array (enclosed in braces) literals, and bumbled along till they threw an error for non-array literals. Throwing an exception appears to be analogous to how Excel operates, rather than something more friendly like a VALUE error. There may be other functions which require similar treatment.
There also remains a TODO for COUNTIFS, and possibly other functions. It appears that PhpSpreadsheet counts booleans for both integer and string compares and probably shouldn't. Again, this is a problem for another day.
* Scrutinizer
Fix one problem.
* Scrutinizer Ignores Its Own Suggested Remedy
Try another approach.
- 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
