 * Multi-level Drop Down Menu (multi-ddm)
 * March 26, 2009
 * Corey Hart @ http://www.codenothing.com
 *
 * @timer: [Default 500] Time in milliseconds to hold menu's open on mouseouts
 * @parentMO: CSS class to add/remove from parent menu on mouseover/mouseouts
 * @childMO: CSS class to add/remove to ALL child menus
 * @levels: Array of CSS classes in order of appearance on drop downs
 * @parentTag: List type of the parent menu ('ul' or 'ol')
 * @childTag: List type of each menu level ('ul' or 'ol')
 * @tags: List type of each level in order ('ul' or 'ol' for each)
 * @numberOfLevels: [Default 5] Number of levels the menu has. Will default to 
 * 	length of levels array when childMO is null.
