I agree with Skip, we mustn't have a 'wroteheader' flag internal to the 
NamedTupleWriter.

Currently to write a 'header' row with a csv.writer you could (for 
example) pass a tuple of header names to writerow. NamedTupleWriter
is no different, you would have a namedtuple of header names instead of
a tuple of header names.

I would not like to see another flag added to the initialisation process
to enable the writing of a header row as the 'first' (or any) row 
written to a file.  We could add a function 'writeheader' that would
write the contents of 'fieldnames' as a row, but I don't like the idea.

Cheers,
