title: process.env.EDGE_APP_ROOT what is?
body: <p>I'm almost done refactoring code taken from here:
  <a href="https://github.com/agracio/edge-js-quick-start" rel="nofollow noreferrer">https://github.com/agracio/edge-js-quick-start</a></p>
  <p>I've added two classes that handle repeatable code, but I'm stuck in two lines of code. I can't for the life of me figure out what they do. I also don't seem to understand what edge_app_root targets (it's a folder but I suspect it targets some file? )</p>
  <p>process.env.EDGE_USE_CORECLR = 1;
  process.env.EDGE_APP_ROOT = baseNetAppPath;</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
