title: angular2-grid directory is not insalled
body: <p>I am relatively new to angular 2. I want to use angular2-grid directory. What I have done is creating a folder for my application with all necessary starting file and then run <strong>npm-install</strong>. Installation is completed and the demo application is working after I typed <strong>npm start</strong>. Then I want to set up angular2-grid and in the <a href="https://www.npmjs.com/package/angular2-grid" rel="nofollow noreferrer">official website</a>  is saying to use it you simply have to run <strong>npm install angular2-grid</strong>. I tried that but I got some warning like :</p>
  
  <blockquote>
    <p>npm WARN angular2-grid@2.0.1 requires a peer of @angular/core@^2.4.4
    but none was installed. npm WARN angular2-grid@2.0.1 requires a peer
    of rxjs@^5.0.1 but none was installed. npm WARN angular2-grid@2.0.1
    requires a peer of zone.js@^0.7.2 but none was installed.</p>
  </blockquote>
  
  <p>I need some help how to overcome this problem. Any suggestion is welcome.</p>
