title: Angular 2 How can I inject a custom provider into a service?
body: <p>Using typescript, In main.ts I have:</p>
  
  <pre><code>let myProvider = provide("message", { useValue: 'Hello' });
  
  bootstrap(AppComponent, [
    myProvider
  ]);
  </code></pre>
  
  <p>How can I inject this into my service (which is in a different file)? (Keep in mind I'm not using the @Component annotation.</p>
