No getValues method available

I couldn't find an easy way to get the current value(s) rather than using callback methods and locally save the last set value.
It will be great to expose a property to just get the currently selected value(s).

The Ember way I see of doing this is creating a service to back the slider component, which seems weird. I see no problems with using DDAU to manage this component and it's values.
