BDC DrillDown Menu: Change Log

Removed restriction that the menu must be built on a list. In fact, the sub-menus and items can be built with completely arbitrary elements (one item, for instance, need not be the same tag as the next).
Changed the mechanism for placing menu panels away from using margins and to using the relative position 'top' property. This way, menu panels can have margins set without losing them on placement.
Made the menu panels calculate their height and width automatically. This height and width need no longer be set in CSS (and in fact, CSS settings are ignored for these two properties).
Recommented the code and renamed a few variables to make the code clearer
Added scrolling through an additional "scroll pane" div to contain the submenus and the new scroll buttons
Added seven CSS options: scrollPaneClass, scrollUpClass, scrollUpHoverClass, scrollUpClickClass, scrollDownClass, scrollDownHoverClass, and scrollDownClickClass. These all control the scroll pane and the two scroll buttons.
Added the option scrollSpeed to control the speed of menu panel scrolling.
Modified the default title hover CSS class to be a darker blue, rather than black.

Fixed bug that prevented menu panels from lining up properly when padding-top was set
Added specific options (inEasing, outEasing) to allow different easings on drill-down and drill-up
Added specific options (inDuration, outDuration) to allow different animation speeds on drill-down and drill-up
Added combined option direction for ease when in/out animation directions are the same
Added class options titleRootHoverClass, labelHoverClass, and labelInitialHoverClass
Changed the way label hovers work so that the label itself gets the class change unless the branch is split
