So, I'm ok with something going in a working state temporarily, but I would definitely prefer to see the Scrollbar create the dom elements itself and have configurable class or id settings that could be passed in from outside. 

We want these components to be multi-instantiable - IE to be able to use it more than once inside an application. 

By using IDs this limits to a single instantiation.

I would also say, kill juse of jQuery as unnecessary.
