  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
