/**
 * <code>
 * Header/Footer Formatting Syntax taken from Office Open XML Part 4 - Markup Language Reference, page 1970:.
 *
 * There are a number of formatting codes that can be written inline with the actual header / footer text, which
 * affect the formatting in the header or footer.
 *
 * Example: This example shows the text "Center Bold Header" on the first line (center section), and the date on
 * the second line (center section).
 *         &CCenter &"-,Bold"Bold&"-,Regular"Header_x000A_&D
 *
 * General Rules:
 * There is no required order in which these codes must appear.
 *
 * The first occurrence of the following codes turns the formatting ON, the second occurrence turns it OFF again:
 * - strikethrough
 * - superscript
 * - subscript
 * Superscript and subscript cannot both be ON at same time. Whichever comes first wins and the other is ignored,
 * while the first is ON.
 * &L - code for "left section" (there are three header / footer locations, "left", "center", and "right"). When
 * two or more occurrences of this section marker exist, the contents from all markers are concatenated, in the
 * order of appearance, and placed into the left section.
 * &P - code for "current page #"
 * &N - code for "total pages"
 * &font size - code for "text font size", where font size is a font size in points.
 * &K - code for "text font color"
 * RGB Color is specified as RRGGBB
 * Theme Color is specifed as TTSNN where TT is the theme color Id, S is either "+" or "-" of the tint/shade
 * value, NN is the tint/shade value.
 * &S - code for "text strikethrough" on / off
 * &X - code for "text super script" on / off
 * &Y - code for "text subscript" on / off
 * &C - code for "center section". When two or more occurrences of this section marker exist, the contents
 * from all markers are concatenated, in the order of appearance, and placed into the center section.
 *
 * &D - code for "date"
 * &T - code for "time"
 * &G - code for "picture as background"
 * &U - code for "text single underline"
 * &E - code for "double underline"
 * &R - code for "right section". When two or more occurrences of this section marker exist, the contents
 * from all markers are concatenated, in the order of appearance, and placed into the right section.
 * &Z - code for "this workbook's file path"
 * &F - code for "this workbook's file name"
 * &A - code for "sheet tab name"
 * &+ - code for add to page #.
 * &- - code for subtract from page #.
 * &"font name,font type" - code for "text font name" and "text font type", where font name and font type
 * are strings specifying the name and type of the font, separated by a comma. When a hyphen appears in font
 * name, it means "none specified". Both of font name and font type can be localized values.
 * &"-,Bold" - code for "bold font style"
 * &B - also means "bold font style".
 * &"-,Regular" - code for "regular font style"
 * &"-,Italic" - code for "italic font style"
 * &I - also means "italic font style"
 * &"-,Bold Italic" code for "bold italic font style"
 * &O - code for "outline style"
 * &H - code for "shadow style"
 * </code>
