Fix #1310, which was closed as stale in 2020, but which I will now reopen. Supersedes PR #1311 (@jaiminmoslake7020), from which I will remove the stale label but leave closed. The issue and the PR were too limited - they detected that the use of two equal signs at the start of a string made for an invalid formula, but there are variations, trivial and otherwise, which might also be detected. Using `setValue` with a string which starts with an equal sign will now attempt to parse (not evaluate) the formula; for certain situations in which the parser throws an exception, the string will be treated as a string rather than a formula. An example where it will still be treated as a formula is a 3D range reference, where the problem is not that it can't be parsed, but rather that the formula isn't supported (see unit test Calculation/Engine/RangeTest::test3dRangeEvaluation). Allowing such a formula might cause problems later on, but that is already what happens. A string beginning with an equal sign but which isn't treated as a formula will automatically set the `quotePrefix` attribute to `true`; all other `setValue` attempts will set it to `false`. This avoids the problem of a lingering value causing problems later on. It has long been a matter of discontent that setting a style can change the selected cells. A new method is added to `Worksheet`: ```php applyStylesFromArray(string $coordinate, array $styleArray) ``` This will attempt to guarantee that the active sheet in the current spreadsheet, and the selected cells in the current worksheet, remain undisturbed after the call. The setting of `quotePrefix` above is the first use of the new method.
