title: Modifying Yeoman Angular generator to use folder other than app
body: <p>I have an existing project with a directory structure like public/angular/ . But in angular generator everything goes to app . How can I modify that behaviour and customise it ? .For starters I am just trying to change app folder to public/angular/</p>
  
  <p>I tried first by changing the </p>
  
  <pre><code> this.env.options.appPath = 'public/angular';
  </code></pre>
  
  <p>But this caused erratic behaviour casing some file to go into public/angular and rest into app/ . Currently bower_components and views and others(404.html and favicon.ico) are stuck in app/ rest are in public/angular</p>
