   I'm sorry so say that you're not helping your PR here :-( You should provide 
some kind of description for this PR so that people can learn what problem this 
PR attempts to solve and how. This would then allow reviewers to try to 
understand if this code belongs here and how it can fit in. I suppose you could 
fill in the Javadoc at a later phase of your development (but before any merge 
into Commons CSV.)
   
   If you want to export database rows, you can use 
`org.apache.commons.csv.CSVPrinter.printRecords(ResultSet)` which works with 
Java's own JDBC framework. The printer class also provides other types of 
services to create CSV files.
   
   More importantly, I see zero reuse of Commons CSV's code for which this PR 
seems to duplicate features like using your `ExportParam` instead of CVS's 
`CSVFormat`. It seems this PR is complete;y standalone code from Commons CSV 
since it does not reuse any of Commons CSV's code. Why would it belong within 
Commons CSV?
