Functions
CLI11_INLINE path_type	CLI::detail::check_path (const char *file) noexcept
	get the type of the path from a file name
template<typename T>
std::enable_if< std::is_signed< T >::value, T >::type	CLI::detail::overflowCheck (const T &a, const T &b)
	Do a check for overflow on signed numbers.
template<typename T>
std::enable_if<!std::is_signed< T >::value, T >::type	CLI::detail::overflowCheck (const T &a, const T &b)
	Do a check for overflow on unsigned numbers.
template<typename T>
std::enable_if< std::is_integral< T >::value, bool >::type	CLI::detail::checked_multiply (T &a, T b)
	Performs a *= b; if it doesn't cause integer overflow. Returns false otherwise.
template<typename T>
std::enable_if< std::is_floating_point< T >::value, bool >::type	CLI::detail::checked_multiply (T &a, T b)
	Performs a *= b; if it doesn't equal infinity. Returns false otherwise.
CLI11_INLINE std::pair< std::string, std::string >	CLI::detail::split_program_name (std::string commandline)
using	CLI::CustomValidator = Validator
	Alias for Validator for custom Validator for clarity.
const detail::ExistingFileValidator	CLI::ExistingFile
	Check for existing file (returns error message if check fails).
const detail::ExistingDirectoryValidator	CLI::ExistingDirectory
	Check for an existing directory (returns error message if check fails).
const detail::ExistingPathValidator	CLI::ExistingPath
	Check for an existing path.
const detail::NonexistentPathValidator	CLI::NonexistentPath
	Check for an non-existing path.
const detail::EscapedStringTransformer	CLI::EscapedString
	convert escaped characters into their associated values
const Range	CLI::NonNegativeNumber ((std::numeric_limits< double >::max)(), "NONNEGATIVE")
	Check for a non negative number.
const Range	CLI::PositiveNumber ((std::numeric_limits< double >::min)(),(std::numeric_limits< double >::max)(), "POSITIVE")
	Check for a positive valued number (val>0.0), <double>::min here is the smallest positive number.
