This module is function as Categories Menu sidebox for use in storefront.

The main functions of this module are:
It dynamically loads and caches the subcategories without page reload
every time. This based on AJAX and the Yahoo! User Interface Library.
It uses optimized algorithm to build the categories tree and count
the products in the categories.

So this mean less SQL calls for the display of Category Menu.
Only 2 queries (and +1 little) used to build the categories tree.
After that, the categories menu represented by a dual linked tree.
And it does not depended on the trees depth.
By using AJAX it dynamically (on demand) populate categories tree
and caching it on the user side.

This menu also has a noscript version.

About this update:
-------------------------------------------------------------------------

Why this update?
Under ZC v1.3.x, the YahooTreeMenuWithAJAX for Zen-Cart v 1.2.7 v0.3a
can be used with the classic template.

However, it have problems if used
with template_default based templates, especially under IE in my case.

This updated the YahooTreeMenuWithAJAX for Zen-Cart v 1.2.7 v0.3a to more
compatible with Zen-Cart v 1.3.x and its templates.

It use more override of Zen Cart and with minor codes changed mainly
for the HTML validation.
