Marquee: Display a marquee that scrolls automatically

This object can be used to display a marquee that scrolls automatically.

It can make the elements inside a given element appear scrolling either horizontally or vertically, so as one contained element disappears the following element appears.

Optionally, the scrolling may stop if the user drags the mouse pointer over the scrolling element.

The scrolling speed, the scrolling direction and the elements seperator are also configurable options.
