Overview

Null logger implementation that just ignores everything. This is used by classes that are intended to be reused outside of Chef, but need to offer logging functionality when used by other Chef code.

It does not define the full interface provided by Logger, just enough to be a reasonable duck type. In particular, methods setting the log level, log device, etc., are not implemented because any code calling those methods probably expected a real logger and not this “fake” one.
