/*
function mn_showMenu(number of menu); Opens top-level menu
function mn_outOfMenu(); Closes all menu after timeout
function mn_itemOn(name of item); Opens next level menu if any
function mn_itemOff(name of item); Closes submenu if any
Name of item MUST BE IN ITS STANDARD FORM e.g. "item4_5.2" where 4 is top-level menu,
5 is second-level menu and 2 is order of item in this menu.
If "mn_firstMenuTimeout" variable is set than first top-level menu will be opened after
specified timeout.
If "mn_widthOfScreen" and/or "mn_heightOfScreen" variable is set then all menu are
positioning relatively to that default value. (suitable for centered content when
window resize event occures)
If "mn_doNotHideFlash" is set to true and IE6 detected, Flash is not hidden if menu
opens above it.
If "mn_relativePositions" array is set then new opening menu is relatively positioned
to element with id which consist of "mn_glue" + menu number, eg. "mn_glue3" for top-level
menu number 3. Under 'x' is set movement (positive or negative) to right, under 'y' is
set the same way movement down. Under 'inheritWidth' is boolean if menu should inherit
width from element which is associated to. Under 'direction' is set direction where menu
is open.
All other functions are for privat purposes ONLY!
ALERT! All OBJECT tags with FLASH must be enclosed by DIV with absolute or relative pos.
