DoubleSlider
DoubleSlider is a Script to give you a Slider Component with two knobs instead of one. It provides horizontal and vertical Sliding.

How to use
The best way to use the DoubleSlider is to initialize it onDomReady. The first argument is the DoubleSliders "container" which contains the knobs. Options can be given as the second argument.
DoubleSlider also provides start, drag, and complete events.
Javascript
var doubleslider = new DoubleSlider(
'doubleslider',
{
range: [0, 8],
start: [1, 7]
}
);
