//** 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"

//* Optimized using http://www.xtreeme.com/javascript-optimizer/ on 1/15/2009 */
