init:    fn(bufio: Bufio);
getline: fn(fd: ref Bufio->Iobuf): list of string;
quote:   fn(s: string): string;

Init must be called before any other operation of the module. Bufio is the instance of the bufio(2) module that will provide the open files to be read.

Getline reads a sequence of fields in csv format from Iobuf fd, unquotes fields as required, and returns them in order in a list. It returns nil on end-of-file (or read error). An empty line is regarded as containing a single empty field.

Quote returns string s quoted as required by the csv format: the result is quoted if s contains comma, newline, or a quote (and all embedded quotes are doubled).
