title: angular2 toaster - No Toaster Containers have been initialized to receive toasts
body: <p>i am using <a href="https://www.npmjs.com/package/angular2-toaster" rel="noreferrer">angular2-toaster</a> in my angular app </p>
  
  <p>it is very simple, </p>
  
  <p>you define toaster container in  the template of  component </p>
  
  <pre><code>&lt;toaster-container&gt;&lt;/toaster-container&gt;
  </code></pre>
  
  <p>and you use toasterService of type <code>ToasterService</code> to pop op toaster </p>
  
  <pre><code>  this.toasterService.pop('success', 'Args Title', 'Args Body');
  </code></pre>
  
  <p>but there is a problem with this approach, I would not  like  to define a container in 
  every component I intend to pop a toaster,
   I would like to define it once in root component. where application bootstrap 
  but when I do so, I get the error </p>
  
  <pre><code> No Toaster Containers have been initialized to receive toasts.
  </code></pre>
  
  <p>any solution? </p>
