title: 404 error when trying to load ADAL.js ins Angular2
body: <p>Anyone have any ideas why I would get a 404 when trying to execute: import 'expose?AuthenticationContext!../../../node_modules/adal-angular/lib/adal.js';</p>
  
  <p>The path is correct and the adal.js file is definitely there (if I paste in the URL into another tab in the browser it opens). I loaded "expose" (with a lot of warning messages).  Here is the full error</p>
  
  <p>Error loading <a href="http://localhost:56580/expose?AuthenticationContext!http://localhost:56580/node_modules/adal-angular/lib/adal.js" rel="nofollow noreferrer">http://localhost:56580/expose?AuthenticationContext!http://localhost:56580/node_modules/adal-angular/lib/adal.js</a> as "expose?AuthenticationContext!../../../node_modules/adal-angular/lib/adal.js" from <a href="http://localhost:56580/app/components/domain/auth.provider.js" rel="nofollow noreferrer">http://localhost:56580/app/components/domain/auth.provider.js</a></p>
