Logger is a middleware that logs the start and end of each request, along with some useful data about what was requested, what the response status was, and how long it took to return. When standard output is a TTY, Logger will print in color, otherwise it will print in black and white.
Logger prints a request ID if one is provided.
Logger has been designed explicitly to be Good Enough for use in small applications and for people just getting started with Goji. It is expected that applications will eventually outgrow this middleware and replace it with a custom request logger, such as one that produces machine-parseable output, outputs logs to a different service (e.g., syslog), or formats lines like those printed elsewhere in the application.
