- The screenshots are not entirely up to date (yesterday snapshot). Index views were improved again.

Features:
- No frontend framework
- Semantic, responsive
- Plain modern look
- Optional LESS file supplied to get going with rapid development and adapting (the layout.ctp and webroot files will go into another PR against cakephp/app)
- No CSS class or div soup (see http://ruby.bvision.com/blog/please-stop-embedding-bootstrap-classes-in-your-html )
