// Dynamic Agenda 
// 
//    * Start by setting iNumAgendas to the correct number of agenda items, and copy/paste arrays to match the number of agendas
//
// For LIVE event:
//
//    * In the "Webcast Parameters" section at the top of this script set the default head, title and slide.
//
//    * For each agenda point set agAlias to a short & unique name (such as "qanda"), and set agDisplayText to a full text name
//      (such as "Questions and Answers", this will appear in agenda.htm)
//
//    * You do not need to set anything in agHeads, agTitles and agSlides for the live event.
//
// For ARCHIVE event:
//
//    * For each agenda point in agAlias, make sure there is a corresponding ASX file for both SAS and VAS and set the "starttime"
//      in each file.
//
//    * For each agenda point set agSlides, agTitles and agHeads to the path to the HTML files that should appear when a user 
//      clicks on the corresponding agenda link.
