/**
 * 
 *	A DHTML accordion based on the Accordion Component found in MooTools: http://mootools.net/docs/more/Fx/Fx.Accordion
 *  The class name of the container that contains the label is always "toggler" and the class name of the container that holds the
 *  content is "elements".  If anyone has a suggestion on how to set this programatically please email me at jlmiller@kahalawai.com
 *  
 *  @binding display - (integer: defaults to 0) The index of the element to show at start (with a transition). To force all elements to be closed by default, pass in -1.
 *  @binding show - (integer: defaults to 0) The index of the element to be shown initially.
 *  @binding trigger - (string: defaults to 'click') The event that triggers a change in element display.
 *  @binding height - (boolean: defaults to true) If set to true, a height transition effect will take place when switching between displayed elements.
 *  @binding width - (boolean: defaults to false) If set to true, it will add a width transition to the accordion when switching between displayed elements. Warning: CSS mastery is required to make this work!
 *  @binding opacity - (boolean: defaults to true) If set to true, an opacity transition effect will take place when switching between displayed elements.
 *  @binding fixedHeight - (boolean: defaults to false) If set to true, displayed elements will have a fixed height.
 *  @binding fixedWidth - (boolean: defaults to false) If set to true, displayed elements will have a fixed width.
 *  @binding alwaysHide - (boolean: defaults to false) If set to true, it will be possible to close all displayable elements. Otherwise, one will remain open at all time.
 *  @binding initialDisplayFx - (boolean; defaults to true) If set to false, the initial item displayed will not display with an effect but will just be shown immediately.
 *  @binding resetHeight - (boolean; defaults to true) If set to false, the height of an opened accordion section will be set to an absolute pixel size.
 *	@binding onActive - (function: signature = function(toggler, element) {}) a method that is called on the container that is opened.
 *	@binding onBackground - (function: signature = function(toggler, element) {}) a method that is called on the container that is closed.
