Functions
UG_API void	ug::AppendCounterToString (std::string &str, std::string indicator, int counter, int maxCounter=-1)
	appends a counter number to a string
UG_API std::string	ug::AppendSpacesToString (std::string &str, int totalLength)
	padding a string with spaces to predefined length
UG_API std::string	ug::ConfigShift (std::string s)
	returns a "shifted" string one-line strings are not shifted two line strings are shifted like this: input: "MyLine1\nMyLine2\n" Output: "\n | MyLine1\n | MyLine2" note that they get an additional at the beginning, and doubled and at the end are removed, so you can use ConfigShift like this
