// dhtml_pages
// created by: Michael Sean Hansen
// 3 Oct 2008
//
// Description:
//    Breaks lengthy content into nice-looking,
//    fast-loading pages.
//
// Usage:
// 1) Place <div id="dhtml_page_buttons"> </div>
//    where you want the buttons to appear.
// 2) Place the content for each page in
//    divs of class "dhtml_page".
//
// Optional:
//    As is, you will see all of the pages displayed
//    for a split second before they are hidden. To
//    avoid this, add the following to a css file:
//      
//    .dhtml_page{ display:none;}
//
// Styling:
//    The buttons are placed within dhtml_page_buttons.
//    It consists of an unordered list with a link in
//    each, so style those to your heart's content!
//
