A simple range slider made in Swift.
This control uses the target-action pattern for change notifications.
In order to be notified when either thumb value changes, register for .ValueChanged:
let rangeSlider = RangeSlider(frame: frame) rangeSlider.addTarget(self, action: "rangeSliderValueChanged:", forControlEvents: .ValueChanged)
