 * This object represents the current context of a given CSV file being either read or written to. The lineNumber is the
 * actual line number (beginning at 1) of the file being read or written to. The rowNumber (beginning at 1) is the
 * number of the CSV row (which will be identical to lineNumber if no rows span multiple lines) - the last rowNumber
 * will correspond with the number of CSV records. The columnNumber (beginning at 1) is the number of the CSV column.
