cart

Improve the tier prices feature - add info like "Buy 2 in x.xx$ and save x%"

Hi,

I was trying to get the associated model from the cart item with $cartItem->model. However, it returns null.

I have seen that in CartItem class there is a call to the associatedModel function within __get method:

    /**
     * Get an attribute from the cart item or get the associated model.
     *
     * @param string $attribute
     *
     * @return mixed
     */
    pub

Eventually the use of NAMESPACES could help with a number of things including packaging the plugin much easier into CoCart Pro and speed for those using PHP 8+

The solution I'd like

Include namespaces on all PHP files that are using a class system. This does not include global functions or template files, just class files.

Example

namespace CoCart\CoCartLite\RestAPI;
