title: Undefined error when trying to use ngDialog
body: <p>I used bower to install the ngDialog module- see <a href="https://github.com/likeastore/ngDialog" rel="nofollow">here</a> I am trying to instantiate the module in my app.js file with the rest of my dependencies, like so:</p>
  
  <pre><code>var app = angular.module('myApp', [
      'ngResource',
      'ngRoute',
      'ngCookies',
      'ui.bootstrap',
      'ngDialog',
      'myApp.services',
      'myApp.directives',
      'myApp.controllers',

  <pre><code>Uncaught Error: [$injector:modulerr] Failed to instantiate module myApp due to:

  </code></pre>
  
  <p>Can anyone advise why?</p>
