well, current_menu starts out as a null value. whenever a menu is shown,
current_menu is set to the id of the menu that's being shown. then, next
time a menu is displayed, the function checks to see if there's a menu
already being shown. if so, it hides it. if the menu to be shown is
different than current_menu, then that menu is displayed. if the
current_menu and the menu that's to be toggled are the same that means the
menu is already open. so, close it and set current_menu back to null.
did that make sense?
