Call these in a timeout

try not to block the ui
Tweak easing and timings

Make them slightly quicker and not overlap a non 1/60th
Use ease-in-out slightly nicer effect
Optimization - low hanging fruit

- Avoid creating an extra nested DIV
 - use the features in Backbone.View
- Use DOM manipulation instead of jQuery.

Still a source of layout latency caused by my prepending.
It forces everything to be recalculated. Might be better to
push upwards instead. Not removing the animation classes
causes incomplete animations. Probably chrome trying it's
own drawing.
