# SO CART WILL KNOW WHO'S CART DATA YOU WANT TO MANIPULATE. SEE IMPORTANT NOTICE ABOVE.
# EXAMPLE: \Cart::session($userId); then followed by cart normal usage.
# NOTE:
# the 'id' field in adding a new item on cart is not intended for the Model ID (example Product ID)
# instead make sure to put a unique ID for every unique product or product that has it's own unique prirce,
# because it is used for updating cart and how each item on cart are segregated during calculation and quantities.
# You can put the model_id instead as an attribute for full flexibility.
# Example is that if you want to add same products on the cart but with totally different attribute and price.
# If you use the Product's ID as the 'id' field in cart, it will result to increase in quanity instead
# of adding it as a unique product with unique attribute and price.
