/**
* Parent class of all XSSF headers and footers.
*
* For a list of all the different fields that can be placed into a header or
* footer, such as page number, bold, underline etc, see the follow formatting
* syntax
*
* Header/Footer Formatting Syntax
*
* 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.
*
*
* 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:
*
*
* - &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. SpreadsheetML Reference
* Material - Worksheets 1966
* - &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"
