Implement Array-enabled for ERROR.TYPE() function
Extract ERROR.TYPE() function tests into separate test file
Extract error function tests into separate test files
And thus complete the implemented Information functions
* First steps toward array-enabling the information functions
Also includes moving unit tests out from Functions and into a separate, dedicated Information folder
* Resolve issue with IF(), branch pruning and calculation cache (ensure that we don't convert the if condition to a bool before we've tested to see if it evaluates to an error)
More refactoring
* isFormula Referencing Sheet With Space in Title
See issue #2304. User sets a cell to `ISFORMULA(cell)`, where `cell` exists on a sheet whose title contains a space, and receives an error. Coordinates are not being passed correctly to Functions::isFormula; in particular, the sheet name is not enclosed in apostrophes, e.g. `Sheet Name!A1` rather than `'Sheet Name'!A1`. (Note that sheet name was not specified in Cell; PhpSpreadsheet adds it before calling isFormula.) Sheets without embedded spaces (or other non-word characters) are handled correctly with or without apostrophes, but spaces require surrounding apostrophes.
As part of this investigation, I determined that Excel handles defined names and cell ranges in ISFORMULA (subject to spills), and that PhpSpreadsheet does not. It is changed to handle them. In the absence of spill support, it will use only the first cell in the range.
Existing tests for ISFORMULA used mocking unneccesarily. They are moved to a separate test member, and mocking is no longer used.
* PhpUnit and Jpgraph
35_Char_render.php had previously been a problem only for PHP8+. It is now a problem for PHP7.4, and will therefore be skipped all the time.
In cells with formulas containing conditions like `=IFSUM(A1:A3;"";B1:B3)`
to sum cells from range A1:A3 with empty value in range B1:B3, the function
`Functions::ifCondition()` create in this case the code `=""""` instead of
`=""`, so it didn't work.
Closes#1206
Sheet titles containing " " or "!" will be quoted in formulas. This commit
fixes the lookup of sheets with this kind of title by trimming the quotes
during the lookup.
Without this any defined range referencing a sheet with " " or "!" in the title
name will be lost when reading the workbook from file.
Fixes#928

- RRI() Calculates the interest rate required for an investment to grow to a specified future value
Conditional operators in the selection parameter of COUNTIF
functions were not being parsed properly, causing evaluations
of formulae with such functions to sometimes fail.
Fixes#526Closes#528
This change adds support for newer functions that are prefixed
by _xlfn. (#356). The calculation engine has been updated to
recognise these as functions, and drop the _xlfn. part.
It also add a couple of the new functions such as STDEV.S/P,
MODE.SNGL, ISFORMULA.
