This generic interface for loggers supports logging a string at one of four different levels (debug, info, warn, error). It's designed to be compatible with Node's console as well as commonly used logging packages and is tested against a few of them. Below are the logging libraries we test for compatibility against.

bunyan

`
const logger = bunyan.createLogger();
`

log4js

`
const logger = log4js.getLogger();
`

loglevel

`
const logger = loglevel.getLogger();
`

winston

`
const logger = winston.createLogger();
