title: Catch Angular 2 exceptions
body: <p>If Angular 2 encounters an internal exception, it won't be logged to the console.</p>
  
  <p>How can I detect such exceptions like the following one? </p>
  
  <pre><code>EXCEPTION: Error during instantiation of MainFormComponent!.
  ORIGINAL EXCEPTION: TypeError: Cannot set property 'crashMeMaybe' of undefined
  ORIGINAL STACKTRACE:
  ... stacktrace ...
  ERROR CONTEXT:
  ... context object ...
  </code></pre>
  
  <p>Are there any available subscriptions? Where is such documentation? </p>
