 // the table for more information.

//////////// JESSE ARRAY EXAMPLE FILE ////////////
Quick Usage:

    // Add product to Cart in Session
    $this->ShoppingCart->addItem($id);

    // Output Order Details
    pr($this->ShoppingCart->getOrderDetails());

The actual generated array in my Session after implementation:
