title: iText7 - How to set up LoggerFactory?
body: <p>I just started using iText today so I started by running the example in Tutorial #1. Unfortunately I get these error messages:</p>
  
  <pre><code>Exception thrown: 'System.NullReferenceException' in itext.io.dll
  iText.IO.Log.LoggerFactory: No logger factory was bound. Defaulting to no-operation logger implementation.
  iText.IO.Log.LoggerFactory: In order to bind a logger factory use     iText.IO.Log.LoggerFactory.BindFactory().
  </code></pre>
  
  <p>Obviously I haven't set up something called LoggerFactory.  How do I do that?</p>
