// global state/variables: must be set before calling qs_start_doc
// most are kept the same for all page sets 
//
// CONVENTIONS: 
// -----------
// IMAGES: 
//   img directory for images 
//   img/trans.gif: transparent one pixel image 
//   img/qsbg.jpg: height 1px, width=real wide, 2pixel in color scheme color
//   img/qslogo.jpg:  logo adapted to color scheme 
//
// COLOR VARIABLES 
//   var qs_page_color: scheme's foreground color 
//   var qs_link_color: scheme's foreground color
//   var qs_link_hover: color sufficiently diffent from foregound color
//   var qs_background_color: color scheme foreground color 
//   var qs_background:  color used for off white background in background image
// 	img/qspagecolor.jpg 1 pixel in color scheme color 
//
// MENU
//   the menu is build on the basis of the global qs_menu_target array variable
//   the function qs_build_menu_table builds the main menu on the left of the 
//   web page, qs_menu_across builds the menu references at the bottom of the 
//   page.  qs_location and qs_location_ref are helper fcts. All these functions//   are specific to page sets (Sweden has its own, so does Concorde, ....)
// 
// A minimal web page with menu is build as follows: 
//    1) include this file 
//    2) add script section with: 
//            qs_path = <PATH to this file";
//            qs_plain_doc_start('Menu Item', 'Submenuitem');
//            qs_body_start(true);
//            html();
//    3) page contents 
//    4) script section with 
//            qs_doc_finish("DATE"); 
//            html(); 
// 
// A minimal web page without menu is build as follows: 
//    1) include this file 
//    2) add script section with: 
//            qs_path = <PATH to this file";
//            qs_img_doc_start('Menu Item', 'Submenuitem', 'headline');
//            html();
//    3) page contents 
//    4) script section with 
//            qs_img_doc_finish("DATE");
//            html(); 
//
// optionally the following functions may be called: 
//   qs_doc_title(text)   == set the title to text instead of default string
//   qs_doc_headline(text) == underline headline at beginning of page contents
//
//   qs_spacer_row(w, h) == add a transparent spacer row, sizes are in pixels
//                          maybe called just before qs_doc_finish
//   qs_menu_set_bling_html(html) == insert html above menu
