Integrate uniformjs into apps, styling drop-down select arrow

I’ve seen posts on how to include 3rd party libraries either in prod/third or by using the libraries function in the app itself. Does anyone know how to integrate this? -> http://uniformjs.com/ If anyone knows anything better/simpler, I really only need to style the button on the select fields. I can change the field css all day to whatever I want in events but the button stays the default browser button.
