* Cookie parser:
*
* Parse _Cookie_ header and populate `req.cookies`
* with an object keyed by the cookie names. Optionally
* you may enabled signed cookie support by passing
* a `secret` string, which assigns `req.secret` so
* it may be used by other middleware.
*
* Examples:
*
* connect()
* .use(connect.cookieParser('optional secret string'))
* .use(function(req, res, next){
* res.end(JSON.stringify(req.cookies));
* })
*
* @param {String} secret
* @return {Function}
* @api public
