        static Justification of​(String format)
        This method parses the given format as Justification. It therefore expects the following format:
        «filler»«alignment»«width»[«mode»]
        The segments have the following meaning:
        segment pattern meaning
        «filler» . character used to fill up with
        «alignment» [+-~] align to the right(+), left(-) or centered(~)
        «with» [0-9]+ if the length of the string to justify is less than this width, the string will be expanded using the filler according to the alignment.
        «mode» [|] if the mode is truncate(|) then the string will be truncated if its length is greater than «with» so the result will always have the length of «with». Please note that truncate can remove valuable information or cause wrong results (e.g. "10000" with a justification of " +3|" will result in "100").
        Examples:
        value justification result
