(Sorry it took a while to send the PR, just go around to doing it this afternoon)

Yes! I didn't add it cause I don't know a lot about the different transports available for this integration.

Winston is a widely supported logging lib in the javascript community, i really liked how it provides the same capabilities of the default logging lib from python, which allows you to handle a single log event in multiple levels and different ways. So if you want, for example, to:

• Route every error log to Rollbar you can add a transport layer that handles only error logs;
• Have a debug transport that logs to a rotating file on disk, you can add a transport to disk;
• Have specific logging being sent to Cloudwatch/Loggly/New Relic or any other logging service available, you most certainly will have a transport ready to use. As each transport can have its own configuration, you can log in different ways to each transport.

(As you can see I really liked the transport settings xP)

Since it provides all these available configurations, it is better than the console.* for complex/sensitive projects. And the formatting really makes it easier to read the logs, either on console or anywhere else.
