Add exportArray Method for Styles (#1580)
Issue #580 has gone stale since I started work on this.
Nevertheless, this implements an exportArray function as an
exact counterpart of applyFromArry.
I chose the name exportArray to avoid confusion with the existing
method getStyleArray, which does something completely different.

This change also increases coverage for all the Style classes to 100%,
with the exception of Style.php itself. There were several (unchanged)
places in Style.php where I did not have sufficient understanding of
what was supposed to be happening, so could not create tests.

All properties used by applyFromArray are exported by this method.
Note that conditional styles are not covered; this is consistent
with the fact that they are not covered by applyFromArray.

The method is implemented as a final public function in Style/Supervisor,
which calls abstract protected function exportArray1, which is implemented
in each of the subclasses, and which calls final protected
function exportArray2 in Style/Supervisor.
So exportArray is usable for any of the subclasses as well.

The new method is added to the documentation.
The existing documentation for applyFromArray was alphabetized to make
it easier to follow.
One property (Style quotePrefix) was added to the documentation.
Some Borders pseudo-properties (vertical, horizontal, and outline) were
documented as usable by applyFromArray,
but aren't actually supported - they were removed.
The documentation of the properties seemed to use setProperty and
getProperty fairly randomly - it now uses setProperty exclusively.

New constants were added for the textRotation "angles" used to create a
"stacked" cell. I felt that changing the readers and writers to use
these constants was beyond the scope of this change, but it is
on my to-do list.

Named formula implementation, and improved handling of Defined Names generally (#1535)
* Initial work modifying the way named ranges are stored, and handled by the calculation engine
This should provide better support for:
  - both union and intersection operators in composite named range values
  - MS Excel implementation of the union operator duplicating values
  - named formulae
  - named ranges and formulae that reference other named ranges and formulae
  - ranges and formulae that reference multiple ranges across multiple worksheets

* Initial work on handling defined names (named ranges and named formulae) correctly
 - UTF-8 names (already extracted as a separate PR and merged)
 - distinction between named ranges and named formulae
 - correct handling of union and intersection operators in named ranges
 - correct evaluation of named range operators in calculations
 - calculation support for named formulae
 - support for nested ranges and formulae (named ranges and formulae that reference other named ranges/formulae) in calculations

* Minor tweaks before resolving merge conflicts

Fix For #1509 (#1518)
* Fix For #1509

User expected no CSV enclosures after $writer->setEnclosure(''),
which had been changed to be consistent with $reader->setEnclosure('').
Writer will now omit enclosures after code above; no change to Reader.
Tests have been added for this condition.

* Add Option to Write CSV Enclosure Only When Required

Allowing the user to specify no enclosure when writing a CSV can lead to
a situation where PhpSpreadsheet (likewise Excel) will not read the
resulting file as intended, e.g. if any cell contains a delimiter character.
This is demonstrated in new test TestBadReread.
No existing setting will rectify this situation.

A better choice would be to add an option to write the enclosure
only when it is needed, which is what Excel does. The RFC4180 spec at
https://tools.ietf.org/html/rfc4180
states when it is needed - when the cell contains the delimiter,
or the enclosure, or a newline.
New test TestGoodReread demonstrates that the file is read as intended.

The documentation has been updated to describe the new function,
and to change the write example where the enclosure is set to null.

* Scrutinizer Suggestions

3 minor changes, all in tests.

Owen Leibman edc411e6dd Add ability to save edited Html/Pdf
We give users the ability to edit Html/Pdf, but it's a little cumbersome
to use the edited Html for an Html file, and difficult to use it
for a Pdf. I believe we could make it fairly painless in both cases
by allowing the user to set a callback to edit the generated Html.
This can be accomplished with fewer than a dozen lines of very simple code.
I think this would be easier than grabbing the Html in pieces,
editing it, and reassembling it. I think it would also be simpler
than an alternative I considered, namely the addition of a new method
(e.g. saveEditedHtml) to each of the Html and Pdf writers.

One edit that users might like to make when editing html is to add
fallback fonts, something that is not currently available in
PhpSpreadsheet, and might be difficult to add. A natural extension to
that idea would be the use of webfonts, something which is guaranteed
difficult to add. See samples/Basic/17b_Html for an example of this.

None of the PDF writers support webfonts yet. That doesn't mean they
won't do so in future, but, for now, samples/Pdf/21a_Pdf is a prosaic
example of something you could do with this callback. In fact, this
opens the door to letting the user replace the entire body with data
of their choosing, effectively allowing PhpSpreadsheet (where you can
set things like paper size and orientation) to be used as a front-end to
the Pdf processor without the user having to be be overly familiar with
the vagaries of the PDF processor. I think this is actually a pretty
nice idea. YMMV. See samples/Basic/21b_Pdf for an example.

Improve HTML Writer (#1464)
There are a number of situations where HTML write was producing
HTML which could not be validated. These include:

  - inconsistent use of backslash terminating META, IMG, and COL tags
  - @page style tags in body rather than header. Aside from being
    non-standard, HTML Reader treats those as spreadsheet data.
  - <div style="page-break-before:always" />, a construct which is
    usually better handled through css anyhow.
  - no alt tag for images (drawings and charts)

Other problems:

  - Windows file names not handled correctly for images
  - Memory drawings not handled in extendRowsForChartsAndImages
  - No handling of different values for showing gridlines
    for screen and print
  - Mpdf and Dompdf do not require the use of inline css.
    Tcpdf remains a holdout in the use of this inferior approach.
  - no need to chunk base64 encoding of embedded images
  - support for colors in number format was buggy (html tags
    run through htmlspecialchars)

Code has been refactored when practical to reduce the number of
very large functions.

Coverage is now 100% for the entire HTML Writer module,
from 75% lines and 39% methods beforehand.

All functions dealing only with charts
are bypassed for coverage because the version of Jpgraph available in
Composer is not suitable for PHP7. The code will, nevertheless,
run successfully, but with warning messages. I have confirmed that
the code is entirely covered, without warnings, when the current
version of Jpgraph is used in lieu of the one available in Composer.
I will be glad to revisit this when the Jpgraph problem is resolved.

Directory PhpSpreadsheetTests/Writer/Html was created to house
the new tests. It seemed logical to move HtmlCommentsTest to
the new directory from PhpSpreadsheetTests/Functional.

A function to generate all the HTML is useful, especially for testing,
but also in lieu of the multiple other generate* functions. I have
added and documented generateHTMLAll.

The documentation for the generate* functions (a) produces invalid html,
(b) produces html which cannot be handled correctly by HTML reader,
and (c) even if those were correct, does not actually affect
the display of the spreadsheet. The documentation has been replaced
by a valid, and more instructive, example.

The (undocumented) useEmbeddedCss property, and the functions
to test and set it are no longer needed. Rather than breaking
existing code by deleting them, I marked the functions deprecated.

This change borrows a change to LocaleFloatsTest from
pull request 1456, submitted a little over a week before this one.


## Improve NumberFormat Support

First phase of this change included correcting NumberFormat handling
in HTML Writer. Certain complex formats could not be handled without
changes to Style/NumberFormat, and I did not wish to combine those changes.

Once the original change had been pushed, I took this part of it back up.
HTML Writer can now handle conditions in formats like:
[Blue][>=3000.5]$#,##0.00;[Red][<0]$#,##0.00;$#,##0.00
In testing, I discovered several errors and omissions
in handling of some other formats.
These are now corrected, and tests added.

Improve Coverage for CSV (#1475)
I believe that both CSV Reader and Writer are 100% covered now.

There were some errors uncovered during development.

The reader specifically permits encodings other than UTF-8 to be used.
However, fgetcsv will not properly handle other encodings.
I tried replacing it with fgets/iconv/strgetcsv, but that could not
handle line breaks within a cell, even for UTF-8.
This is, I'm sure, a very rare use case.
I eventually handled it by using php://memory to hold the translated
file contents for non-UTF8. There were no tests for this situation,
and now there are (probably too many).

"Contiguous" read was not handle correctly. There is a file
in samples which uses it. It was designed to read a large sheet,
and split it into three. The first sheet was corrrect, but the
second and third were almost entirely empty. This has been corrected,
and the sample code was adapted into a formal test with assertions
to confirm that it works as designed.

I made a minor documentation change. Unlike HTML, where you never
need a BOM because you can declare the encoding in the file,
a CSV with non-ASCII characters must explicitly include a BOM
for Excel to handle it correctly. This was explained in the Reading CSV
section, but was glossed over in the Writing CSV section, which I
have updated.
