      Description

      In the current version CSVFormat#withHeader is only used by CSVParser. It would be nice if CSVPrinter also supported it. Ideally, the following line of code

      CSVPrinter csvPrinter
        = CSVFormat.TDF
          .withHeader("x")
          .print(Files.newBufferedWriter(Paths.get("data.csv")));
      csvPrinter.printRecord(42);
      csvPrinter.close();
      

      should produce

      x
      42
      

      If you're alright with the idea of automatically inserting headers, I can attach a patch.
