	 * prev:'img.prev',// Selector to the 'prev' button (absolute!, meaning it's relative to the document)

	 * axis:'xy',// The default is 'y' scroll on both ways
	 * navigation:'#navigation li a',

	 * force:true, // Force a scroll to the element specified by 'start' (some browsers don't reset on refreshes)
	 * queue:false,// We scroll on both axes, scroll both at the same time.
	 * event:'click',// On which event to react (click is the default, you probably won't need to specify it)
	 * stop:false,// Each click will stop any previous animations of the target. (false by default)
	 * lock:true, // Ignore events if already animating (true by default)		
	 * start: 0, // On which element (index) to begin ( 0 is the default, redundant in this case )		
	 * cycle:true,// Cycle endlessly ( constant velocity, true is the default )
	 * step:1, // How many items to scroll each time ( 1 is the default, no need to specify )
	 * jump:false, // If true, items become clickable (or w/e 'event' is, and when activated, the pane scrolls to them)
	 * lazy:false,// (default) if true, the plugin looks for the items on each event(allows AJAX or JS content, or reordering)
	 * interval:1000, // It's the number of milliseconds to automatically go to the next
	 * constant:true, // constant speed
