[Csv] PEP 305

(Let's keep csv at mail.mojam.com in the loop.  This is good input for all of
us.)

I understand that it wasn't quite right.  I had to guess about the quoting.
It's still all wrong.  It's not just that there are extra quotation marks at
the beginning and the end (the ones you stripped), it's that every other
quotation mark is doubled.  The parser only supports a single character
quote character, so they are a problem.

One thing you can do to make like easier is to write a generator function
which sits between the file and the parser.  It will strip the extra quotes
in each line.

I've attached a simple Python script (which requires Python 2.2 or 2.3) that
seems to work correctly, as well as your longs.csv file (with the extra
leading and trailing triple quotes) so the other developers can see it.
