        * Shopping Cart Javascript        -    contains code to convert the Actinic 
        *                                    cart to AJAX call and add popups to 
        *                                    display information.

        * Issue V1.01.0051 a
        * Revised 12/1/2011  V1.00.0041    
        * to add a popup to the form that is used to 
        * add product to cart. This popup displays error messages, and the
        * the Cart popup only appears if products are added to cart.
        * Improved error handling when extracting messages from returned page.
        *
        * Revised 18/1/2011  V1.00.0042 
        * to increase amount of button that is active, added
        * theme margins to cart button pop up.
        * 
        * Revised 22/1/2011  V1.00.0046
        * This version links the main cart pop up to the form itself.
        * 
        * Revised 26/1/2011  V1.01.0047
        * Added new code to attach a popup to the cart summary instead of 
        * using a popup that is displaying the cart contents. This uses
        * code inside the Actinic layouts so that Actinic variables can control
        * how the code works
        * 
        * Revised 6/2/2011 V1.00.0050
        * Added option to select the theme and the popup delay
        * 
        * Revised 9/2/2011 V1.00.0051
        * Removed the close link on a pop up
        * 
        * MUST HAVE FUNCTION
        * showrequest()
        * create_cart_popup()
        * append_basket()
        * in actinic layout for this to work.
