//// code to open/close popup boxes on org charts

// how it works:
//  When the mouse passes over one of the small boxes, it calls
//   startpopup() to open the corresponding popup and close any others
//   that might be open.
//  When the mouse leaves the box, it calls endpopup() to start a delayed
//   close of the pop-up via start_delayed_hide_popup(). The closing is delayed
//   because the mouse might be entering the popup layer. If not, then the popup
//   will either be closed by the delayed call to do_delayed_hide_popup(), or by
//   entering a different box that triggers a new popup.
//  When the mouse enters a popup, it cancels the delayed close of that
//   popup by again calling startpopup().
//  When the mouse leaves a popup, it starts the delayed close by calling endpopup().
//
