      Format strings are used by the algorithm regex_replace and by match_results<>::format, and are used to transform
      one string into another.
    
There are three kind of format string: Sed, Perl and Boost-Extended.
      Alternatively, when the flag format_literal
      is passed to one of these functions, then the format string is treated as a
      string literal, and is copied unchanged to the output.
