  Description:
-    Delete the session & close open browsers. We will try to call this
-    on our down when we get DEMOLISHed, but in the event that we are
-    only demolished during global destruction, we will not be able to
-    close the browser. For your own unattended and/or complicated tests,
-    we recommend explicitly calling quit to make sure you're not leaving
-    orphan browsers around.

  Usage:
     $driver->quit();
