+It affects how the directive will perform DOM manipulation. This allows for complex animations to take place
 without burdening the directive which uses the animation with animation details. The built in directives
 <code>ngRepeat</code>, <code>ngInclude</code>, <code>ngSwitch</code>, <code>ngShow</code>, <code>ngHide</code> and <code>ngView</code> already accept <code>ngAnimate</code> directive.
 Custom directives can take advantage of animation through <a href="api/ng.$animator"><code>$animator service</code></a>.</p>
