Remove jQuery dependency

[Misiu]

I've been playing around with Your directive and I found it really nice.
I had no problem with getting it up and running, but after removing jQuery from my project Your directive stopped working.
One thing I was able to fix was able to fix was element selection.
Instead:
var $element = $(scrollContainer);
I'm using:
var $element = angular.element(document.querySelector(scrollContainer));

but problem remains with:
$element.animate({ scrollTop: scrollPos }, scrollSpeed);
I've found angular-only way to animate, but I'm not angular expert so it's hard for me to combine both.

Thanks for help.
