Functions
void	ola::SetHelpString (const std::string &first_line, const std::string &description)
	Set the help string for the program.
void	ola::DisplayUsage ()
	Print the usage text to stdout.
void	ola::DisplayUsageAndExit ()
	Print the usage text to stdout then exit.
void	ola::DisplayVersion ()
	Print the version text to stdout.
void	ola::ParseFlags (int *argc, char **argv)
	Parses the command line flags up to the first non-flag value. argv is re-arranged so that it only contains non-flag arguments.
