//** Chrome Drop Down Menu- Author: Dynamic Drive (http://www.dynamicdrive.com)

//** Updated: July 14th 06' to v2.0
	//1) Ability to "left", "center", or "right" align the menu items easily, just by modifying the CSS property "text-align".
	//2) Added an optional "swipe down" transitional effect for revealing the drop down menus.
	//3) Support for multiple Chrome menus on the same page.

//** Updated: Nov 14th 06' to v2.01- added iframe shim technique

//** Updated: July 23rd, 08 to v2.4
	//1) Main menu items now remain "selected" (CSS class "selected" applied) when user moves mouse into corresponding drop down menu. 
	//2) Adds ability to specify arbitrary HTML that gets added to the end of each menu item that carries a drop down menu (ie: a down arrow image).
	//3) All event handlers added to the menu are now unobstrusive, allowing you to define your own "onmouseover" or "onclick" events on the menu items.
	//4) Fixed elusive JS error in FF that sometimes occurs when mouse quickly moves between main menu items and drop down menus

//** Updated: Oct 29th, 08 to v2.5 (only .js file modified from v2.4)
	//1) Added ability to customize reveal animation speed (# of steps)
	//2) Menu now works in IE8 beta2 (a valid doctype at the top of the page is required)

//** Accordion Content script: By Dynamic Drive, at http://www.dynamicdrive.com
//** Created: Jan 7th, 08'

//Version 1.3: April 3rd, 08':
//**1) Script now no longer conflicts with other JS frameworks
//**2) Adds custom oninit() and onopenclose() event handlers that fire when Accordion Content instance has initialized, plus whenever a header is opened/closed
//**3) Adds support for expanding header(s) using the URL parameter (ie: http://mysite.com/accordion.htm?headerclass=0,1)

//April 9th, 08': Fixed "defaultexpanded" setting not working when page first loads

//Version 1.4: June 4th, 08':
//**1) Added option to activate a header "mouseover" instead of the default "click"
//**2) Bug persistence not working when used with jquery 1.2.6

//Version 1.5: June 20th, 08':
//**1) Adds new "onemustopen:true/false" parameter, which lets you set whether at least one header should be open at all times (so never all closed).
//**2) Changed cookie path to site wide for persistence feature
//**3) Fixed bug so "expandedindices" parameter in oninit(headers, expandedindices) returns empty array [] instead of [-1] when no expanded headers found

//**1) Version 1.5.1: June 27th, 08': Fixed "defaultexpanded" setting not working properly when used with jquery 1.2.6

//Version 1.6: Oct 3rd, 08':
//**1) Adds new "mouseoverdelay" param that sets delay before headers are activated when "revealtype" param is set to "mouseover"
//**2) Fixed bug with "onemustopen" param not working properly when "revealtype" is set to "click"

//Version 1.7: March 24th, 09': Adds a 3rd revealtype setting "clickgo", which causes browser to navigate to URL specified inside the header after expanding its contents.

//Version 1.7.1: May 28th, 09': Fixed issue that causes margins/paddings in accordion DIVs to be lost in IE8
