create a record from line. The line is one line (or record) read from the text file. The resulting record is an object which. The object takes signals for each field according to the various fields defined with add_field or varients of it.

line_number is an optional line number of the line in a file of records. If line is not in a series of records (lines), omit and it’ll be -1 in the resulting record objects. Just make sure you realize this when reporting errors.
