Class: Accordion
	The Accordion class creates a group of elements that are toggled when their handles are clicked. When one elements toggles in, the others toggles back.
	Inherits methods, properties, options and events from <Fx.Elements>.
	
Note:
	The Accordion requires an XHTML doctype.

Arguments:
	togglers - required, a collection of elements, the elements handlers that will be clickable.
	elements - required, a collection of elements the transitions will be applied to.
	options - optional, see options below, and <Fx.Base> options and events.

Options:
	show - integer, the Index of the element to show at start.
	display - integer, the Index of the element to show at start (with a transition). defaults to 0.
	fixedHeight - integer, if you want the elements to have a fixed height. defaults to false.
	fixedWidth - integer, if you want the elements to have a fixed width. defaults to false.
	height - boolean, will add a height transition to the accordion if true. defaults to true.
	opacity - boolean, will add an opacity transition to the accordion if true. defaults to true.
	width - boolean, will add a width transition to the accordion if true. defaults to false, css mastery is required to make this work!
	alwaysHide - boolean, will allow to hide all elements if true, instead of always keeping one element shown. defaults to false.
	
Events:
	onActive - function to execute when an element starts to show
	onBackground - function to execute when an element starts to hide
