 *  
 * LOTUS CREATIONS AJAX SHOPPING BASKET
 * @author Chris Li
 * @version 0.1
 * @note used in conjunction with JQuery 1.3.2
 * 
 * Shopping basket that interacts with LOTUS CMS to display and generate basket
 * 
 * How to setup:
 * 1.  HTML SETUP - note: this basket could be redesigned if need be
 *  <div id="cart_container" style="">
        <!-- BEGIN ShoppingCartBlock -->                
        <div id="cart-info">                    
            <div class="content">
                <!-- BEGIN CartBlock -->
                    You currently have <strong id="basket-total-items">{basket_total_items}</strong> items in your basket totaling <strong id="basket-total">{basket_total}</strong>
                <!-- END CartBlock -->
            </div>                     
        </div>
        <div id="open-basket">
            <div class="content">
                Open Basket</div>
        </div>
        <div id="checkout">
            <div class="content">
                <a href="{checkout_url}">Checkout</a></div>
        </div>    
        <div class="clear"></div>
        <!-- END ShoppingCartBlock -->
    </div>
    <div id="cart_content_container" style="display:block;">
        <div id="cart_content" style="display:none;"></div>
    </div>
 *
 * 2. Set variables for basket:
 * //init variables for lotus-ajax-basket.js
  var basket_image_loading = "http://192.168.0.100/pariscues-v2/templates/images/loading.gif";
  var get_basket_info_form_action = "http://192.168.0.100/pariscues-v2/index.php?module=ProductsApp&action=ajax_get_basket_info&nav_id=";
  var delete_basket_item_form_action = "http://192.168.0.100/pariscues-v2/index.php?module=ProductsApp&action=ajax_delete_basket_item&nav_id=";
  var ajax_update_quantity_form_action = "http://192.168.0.100/pariscues-v2/index.php?module=ProductsApp&action=ajax_update_quantity&nav_id=";
  var get_basket_totals_form_action = "http://192.168.0.100/pariscues-v2/index.php?module=ProductsApp&action=ajax_get_basket_totals";
  
 *
 * 3. Setup call to basket init
 * $(document).ready(function(){
      //init. functions1
    	toggleBasket();
   });
