title: CustomInjections for log4j2
body: <p>I've been trying to follow the <a href="https://github.com/google/guice/wiki/CustomInjections" rel="nofollow noreferrer">CustomInjections</a> documentation but updating it for log4j2. I seem to be missing the InjectLogger class. </p>
  
  <p>Any ideas what I missed, or does someone have a working example I can see?</p>
