Namespaces
namespace	csv
	The all encompassing namespace.
namespace	csv::internals
	Stuff that is generally not of interest to end-users.

Typedefs
using	csv::RowCollection = internals::ThreadSafeDeque< CSVRow >
	Standard type for storing collection of rows.

Functions
template<typename OutArray , typename T = typename OutArray::type>
CSV_CONST CONSTEXPR_17 OutArray	csv::internals::arrayToDefault (T &&value)
	Helper constexpr function to initialize an array with all the elements set to value.
CSV_CONST CONSTEXPR_17 ParseFlagMap	csv::internals::make_parse_flags (char delimiter)
	Create a vector v where each index i corresponds to the ASCII number for a character and, v[i + 128] labels it according to the CSVReader::ParseFlags enum.
CSV_CONST CONSTEXPR_17 ParseFlagMap	csv::internals::make_parse_flags (char delimiter, char quote_char)
	Create a vector v where each index i corresponds to the ASCII number for a character and, v[i + 128] labels it according to the CSVReader::ParseFlags enum.
CSV_CONST CONSTEXPR_17 WhitespaceMap	csv::internals::make_ws_flags (const char *ws_chars, size_t n_chars)
	Create a vector v where each index i corresponds to the ASCII number for a character c and, v[i + 128] is true if c is a whitespace character.
WhitespaceMap	csv::internals::make_ws_flags (const std::vector< char > &flags)
size_t	csv::internals::get_file_size (csv::string_view filename)

template<typename TStream , csv::enable_if_t< std::is_base_of< std::istream, TStream >::value, int > = 0>
std::string	csv::internals::get_csv_head (TStream &source)
std::string	csv::internals::get_csv_head (csv::string_view filename, size_t file_size)
	Read the first 500KB of a CSV file.
