// In this implementation continuation lines are not supported.
// Escape character is supported. Quoting is supported.
// Empty and blank lines are ignored.
// All non-numeric fields are read as NaNs.
// If the first line has more NaNs than 3rd and 4th lines
// it is assumed that this line is a header. Header is used for column titles.
// Default decimal point is '.'. If option 'decimal-comma' is set both '.'
// and ',' are regarded decimal point.
// Separator is determined automatically by reading the first 3 lines,
// trying 7 separators: "\t,;|:/ ". (If 'decimal-comma' is given, comma
// is not tried as separator.)
// The separator that gives most numbers in lines 3 and 4 is selected.
