Is the order correct here? If there is any error getting devices we would be
left with no UI.

[mbrunson, 2016/12/02 02:31:45]

Yes. That's a possibility. I'll initialize the pages before the Promise chain
runs. Done.

       .catch(function(error) { console.error(error); });
   }
 
   return {
     initializeViews: initializeViews
   };
 });
 
 document.addEventListener(
     'DOMContentLoaded', bluetooth_internals.initializeViews);
