/*
This class applies tooltips to the prizeCarousel list element images.

Tooltip copy is semantically inserted into the list element in the span .tipBlurb. HTML is allowed in the tooltip copy.

It must play nice with the jCarouselLite plugin, since they are both applied to the prize Carousel.
Hovering over a prize image shows a tooltip dynamically placed above the prize.
