How does one use Elmah in ASP.NET 5/vNext/Core?
<p>I am a bit confused about how to use Elmah in the ASP.NET 5 / MVC 6 projects.  I got the package from nuget and it added <code>"Elmah.Mvc": "2.1.2"</code> to dependencies in project.json.</p>

<p>I am not sure where to go from here - back in the day, nuget would add entries to the web.config which is now gone.  And I can't seem to find any examples on their github or elsewhere.   </p>

<p>Am I missing something simple?</p>
