title: I am getting this error "No module: ngResource"
body: <p>Trying to use the Angular $resource, and its coming back as not a method. Looking through the sparse documentation, I was able to find this :</p>
  
  <pre><code>angular.module('productServices', ['ngResource']).
  </code></pre>
  
  <p>That you're supposed to include it in your app module. Fair enough, I throw it in and get :</p>
  
  <pre><code>Uncaught Error: No module: ngResource 
  </code></pre>
  
  <p>Hmm.. does this not come with Angular.js and its a separate plugin?</p>
