Fluent methods, especially setters, return the object on which are
called. This is documented in PHPDoc using the `$this` keyword, which
is equivalent to `static` with the additional notion of object identity.
This helps IDEs and static analysis tools provide more meaningful output.
The `setRange` method of the `Xlsx/AutoFilter` class expects a filter
range format like "A1:E10". The returned value from
`$this->worksheetXml->autoFilter['ref']` could contain "$" and returning
a value like "$A$1:$E$10".

When freeze pane is in use on a worksheet, PhpSpreadsheet saves to Xlsx in such
a way that the active cell is always set to the top left cell below the freeze
pane. I find it difficult to understand why:
1. You have given users the setSelectedCells function, but then choose to
ignore it.
2. Excel itself does not act in this manner.
3. PHPExcel did not act in this manner.
4. PhpSpreadsheet when writing to Xls does not act in this manner.
This is especially emphasized because the one test in FreezePaneTest which
would expose the difference is the only test in that member which is
not made for both Xls and Xlsx.
5. It is *really* useful to be able to open a spreadsheet anywhere, even when
it has header rows.
Closes#1323
Prior to 1.10, all numeric values where read as floats. In 1.10
numeric values are read using 0 + x, which relies on PHP type
juggling rules. As a result, float(0.0) is written as string('0'),
then read back as int(0). This fix causes the writer to retain the
the decimal for float values such that a reader can differentiate
floats from ints.
Closes#1262
Some auto generated xlsx files are using other names as workbook than "workbook.xml".
This is fixed by supporting names of workbooks by regex `/workbook.*\.xml/`.
Closes#1183
Fix: Return #NUM! if values and dates contain a different number of values
Fix: Return #NUM! if there is not at least one positive cash flow and one negative cash flow
Fix: Return #NUM! if any number in dates precedes the starting date
Fix: Return #NUM! if a result that works cannot be found after max iteration tries
Fix: Correct DocBlocks for XIRR & XNPV
Add: Validate XIRR with unit tests
Closes#1177
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.

* Call garbage collector after removing a column
Otherwise callers of getHighestColumn get stale values
* Update changelog
* Fix remove a column out of range removes the last column
Given:
+---+---+
| A | B |
+---+---+
Attempting to remove 'D', should not alter the worksheet
* Avoid side effects when trying to remove more columns than exists
We often want to export a table as an excel sheet. The system renders the
html and it seems like a waste of time to write it to the file system to
use the reader. This allows us to render the html and then just pass it to
a reader
Closes#1136
Calculation engine was resolving every function by first resolving its arguments
including IFs, this was causing significant over evaluation when IFs were used
as it meant for every case to be evaluated.
Introduce elements to identify ifs and enable better branch resolution
(pruning). We tag parsed tokens to associate a branch identifier to them.
Closes#844
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

* Unit tests for BETADIST() and BETAINV()
