Convert logging to winston.

[itotallyrock]

Winston is a very useful library that functions across systems, allows logging levels, and logging to a file. The current library log-util is nice but was only chosen for the pretty colors it offered. Which any serious program doesn't need and will let syslog handle the coloring and formatting and simple logging is all that is necessary.

Winston is one of many possible choices for a new logging library, we first need to think of what we want out of the logging.

What we want

• Easily analyzed (Bunyan is good for this)
  • Searching for specific events
  • Organized based on time
  • Will include any relevant information to the log (if logging a user registered log their user id)
• Controllable logging levels (Pretty much standard in all loggers)
• Works across all platforms

What we don't necessarily need are

• Multiple output destinations
  • Generally speaking logging should only goto stdout or stderr and let log routers handle this
• Fancy printing to console
  • Although it is a plus to have colors and indentation and other features, it is unnecessary for a 12 factor app.
  • There are external printers that exist outside of the app for pretty logging like Bunyan CLI

Knowing this it somewhat narrows it down but it is still a difficult decision. I will be doing more investigating into different libraries.

We will also start using the debug library which will allow for easy console output of finding errors.
