/**
* Format a value according to the standard Excel behavior. This "standard" is
* not explicitly documented by Microsoft, so the behavior is determined by
* experimentation; see the tests.
* <p>
* An Excel format has up to four parts, separated by semicolons. Each part
* specifies what to do with particular kinds of values, depending on the number
* of parts given:
* <dl>
* <dt>One part (example: {@code [Green]#.##})</dt>
* <dd>If the value is a number, display according to this one part (example: green text,
* with up to two decimal points). If the value is text, display it as is.</dd>
*
* <dt>Two parts (example: {@code [Green]#.##;[Red]#.##})</dt>
* <dd>If the value is a positive number or zero, display according to the first part (example: green
* text, with up to two decimal points); if it is a negative number, display
* according to the second part (example: red text, with up to two decimal
* points). If the value is text, display it as is.</dd>
*
* <dt>Three parts (example: {@code [Green]#.##;[Black]#.##;[Red]#.##})</dt>
* <dd>If the value is a positive
* number, display according to the first part (example: green text, with up to
* two decimal points); if it is zero, display according to the second part
* (example: black text, with up to two decimal points); if it is a negative
* number, display according to the third part (example: red text, with up to
* two decimal points). If the value is text, display it as is.</dd>
*
* <dt>Four parts (example: {@code [Green]#.##;[Black]#.##;[Red]#.##;[@]})</dt>
* <dd>If the value is a positive number, display according to the first part (example: green text,
* with up to two decimal points); if it is zero, display according to the
* second part (example: black text, with up to two decimal points); if it is a
* negative number, display according to the third part (example: red text, with
* up to two decimal points). If the value is text, display according to the
* fourth part (example: text in the cell's usual color, with the text value
* surround by brackets).</dd>
* </dl>
* <p>
* A given format part may specify a given Locale, by including something
* like {@code [$$-409]} or {@code [$£-809]} or {@code [$-40C]}. These
* are (currently) largely ignored. You can use {@link DateFormatConverter}
* to look these up into Java Locales if desired.
* <p>
* In addition to these, there is a general format that is used when no format
* is specified.
*
* TODO Merge this with {@link DataFormatter} so we only have one set of
* code for formatting numbers.
* TODO Re-use parts of this logic with {@link ConditionalFormatting} /
* {@link ConditionalFormattingRule} for reporting stylings which do/don't apply
* TODO Support the full set of modifiers, including alternate calendars and
* native character numbers, as documented at https://help.libreoffice.org/Common/Number_Format_Codes
