WIP - nearly fixed all the bugs with the sliceWidget.js. I still have got to
replicate the code for the right handle.
{{! template used by the jquery ui tooltip }}
<div class='Ldt-tooltip'>
<div class='title'>{{title}}</div>
<div class='time'>{{begin}} : {{end}} </div>
<div class='description'>{{description}}</div>
</div>
