the class HistoryManager method buildHistory.

/**
   * <p>Builds a text representation of the scanning history. Each scan is encoded on one
   * line, terminated by a line break (\r\n). The values in each line are comma-separated,
   * and double-quoted. Double-quotes within values are escaped with a sequence of two
   * double-quotes. The fields output are:</p>
   *
   * <ol>
   *  <li>Raw text</li>
   *  <li>Display text</li>
   *  <li>Format (e.g. QR_CODE)</li>
   *  <li>Unix timestamp (milliseconds since the epoch)</li>
   *  <li>Formatted version of timestamp</li>
   *  <li>Supplemental info (e.g. price info for a product barcode)</li>
