//// Usage //
//
// Only need to call the createMarquee() function,
// if desired, pass through the following paramaters:
//
// $1 duration: controls the speed at which the marquee moves
//
// $2 padding: right margin between consecutive marquees.
//
// $3 marquee_class: the actual div or span that will be used to create the marquee -
// multiple marquee items may be created using this item's content.
// This item will be removed from the dom
//
// $4 container_class: the container div in which the marquee content will animate.
//
// $5 marquee-content-sibling : (optional argument) a sibling item to the marqueed item that
// affects the end point position and available space inside the
// container.
//
// $6 hover: Boolean to indicate whether pause on hover should is required.
