title: AngularJS 1.2 - ngAnimate not working
body: <p>I am new to using ng-animate with AngularJS 1.2.  I am not sure why my ng-animate does not work a certain class name but works with the default for a simple fade in that I saw in an example.  </p>
  
  <p>In this example, I try to set my ng-animate class to be 'animation':

  <p>but when I use the default, and my class name for animations is just ".ng-enter" and ".ng-leave", the fade in animation seems to work fine.  </p>

  <p>Any help would be greatly appreciated, thanks!</p>
