-/**
- * @fileoverview Implementation of a range model. This is an implementation of
- * the BoundedRangeModel as described by Java at
- * http://java.sun.com/javase/6/docs/api/javax/swing/BoundedRangeModel.html.
- *
- * One good way to understand the range model is to think of a scroll bar for
- * a scrollable element. In that case minimum is 0, maximum is scrollHeight,
- * value is scrollTop and extent is clientHeight.
- *
- * Based on http://webfx.eae.net/dhtml/slider/js/range.js
