Description

I suggest adding a new method to CSVParser that returns a list of headers. My use case is to create a new CSVPrinter from it that uses different formatting rules.

My current implementation looks like this:

Map<String, Integer> headers = parser.getHeaderMap();
String[] array = new String[headers.size()];
for (Entry<String, Integer> entry : headers.entrySet()) {
   array[entry.getValue()] = entry.getKey();
}

CSVFormat outFormat = CSVFormat.newFormat('|').withHeader(array);

This would become a lot simpler, if I could get the (unmodifiable) list directly from CSVParser.
