title: Using dustjs-helpers with Kraken js
body: <blockquote>
    <p>I created a project using Kraken 1.0.1 with yo kraken, with template engine dustjs, but I can not use functions dustjs-helpers.</p>
  </blockquote>
  
  <p>My config.json:</p>
  
  <pre><code>"express": {
      "view cache": false,
      "view engine": "dust",
      "views": "path:./public/templates"
  },
  
  "view engines": {
      "dust": {
          "module": "engine-munger",
          "renderer": {
              "method": "dust",
              "arguments": [
                  { "cache": false},
                  {
                      "views": "config:express.views",
                      "view engine": "config:express.view engine",
                      "specialization": "config:specialization",
                      "i18n": "config:i18n"
                  }
              ]
          }
      }
  }
  </code></pre>
  
  <p>template.dust (not working helpers)</p>
  
  <pre><code>{@if cond="1&lt;2"}
     &lt;div&gt;  x is less than y and b == c and either e or f exists in the output &lt;/div&gt; 
   {:else}
     &lt;div&gt; x is &gt;= y &lt;/div&gt;
   {/if}
  </code></pre>
  
  <p>template2.dust (working)</p>
  
  <pre><code>        {?messages}
              {#messages}
                  &lt;div data-alert class="alert-box info radius"&gt;
                    {.}
                    &lt;a href="#" class="close"&gt;&amp;times;&lt;/a&gt;
                  &lt;/div&gt;
              {/messages}
          {/messages}
  </code></pre>
  
  <p>Only dusts core working, I add dustjs-helpers with npm. How add dustjs-helpers in my kraken project?</p>
