The default emptyValue is confusing

[zachliu]

These comments say the default value for emptyValue is null:

• univocity-parsers/src/main/java/com/univocity/parsers/common/CommonWriterSettings.java

  Lines 52 to 58 in 7e7d1b3

  	/**
  	* Returns the String representation of an empty value (defaults to null)
  	*
  	* <p>When writing, if the writer has an empty String to write to the output, the emptyValue is used instead of an empty string
  	*
  	* @return the String representation of an empty value
  	*/

• univocity-parsers/src/main/java/com/univocity/parsers/csv/CsvWriterSettings.java

  Lines 29 to 30 in 7e7d1b3

  	* <li><b>emptyValue <i>(defaults to null)</i>:</b> Defines a replacement string to signify an empty value (which is not a null value)
  	* <p>If the writer has an empty String to write to the output, the emptyValue is used instead of an empty string</li>

But the code says otherwise:

univocity-parsers/src/main/java/com/univocity/parsers/common/CommonWriterSettings.java

Line 46 in 7e7d1b3

private String emptyValue = "";

In the "top-level" Csv class, I do see this

univocity-parsers/src/main/java/com/univocity/parsers/csv/Csv.java

Line 66 in 7e7d1b3

settings.setEmptyValue(null);

But it doesn't justify the above code-comment conflict. Unless I'm missing something here 🤔
