	 * Most jQuery.serialScroll's settings, actually belong to jQuery.ScrollTo, check it's demo for an example of each option.
	 * @see http://flesler.webs.com/jQuery.ScrollTo/
	 * You can use EVERY single setting of jQuery.ScrollTo, in the settings hash you send to jQuery.serialScroll.
	 *
	 * The plugin binds 6 events to the container to allow external manipulation.
	 * prev, next, goto, start, stop and notify
	 * You use them like this: $(your_container).trigger('next'), $(your_container).trigger('goto', [5]) (0-based index).
	 * If for some odd reason, the element already has any of these events bound, trigger it with the namespace.
	 *
	 * IMPORTANT: this call to the plugin specifies ALL the settings (plus some of jQuery.ScrollTo)
	 * This is done so you can see them. You DON'T need to specify them all.
	 * A 'target' is specified, that means that #screen is the context for target, prev, next and navigation.
