In general I think this is not nice api to logger as you must write `Logger.log.info`. Better one is if have logger as module, so you can include it into classes.
So add something like:
```
module Logger #rename class to GlobalLogger
  def log
     GloballLogger.instance.log
  end

  def included
   ...
  end
end
```

this way you can have in class `include Logger` and log via `log.info`
