-Nothing crazy here! Just a simple fade in and fade out effect between pages. The only out of the ordinary thing
-here is that we're using absolute positioning to position the next page (identified via `ng-enter`) on top of the
-previous page (the one that has the `ng-leave` class) while performing a cross fade animation in between. So
-as the previous page is just about to be removed, it fades out while the new page fades in right on top of it.
-Once the leave animation is over then element is removed and once the enter animation is complete then the
-`ng-enter` and `ng-enter-active` CSS classes are removed from the element rendering it to be position itself
-with its default CSS code (so no more absolute positioning once the animation is over). This works fluidly so
-that pages flow naturally between route changes without anything jumping around.

 You may be thinking that we're just going to create another CSS-enabled animation.
-Although we could do that, let's take the opportunity to learn how to create JavaScript-enabled animations with the `animation()` module method.
