Commerce Cart Alternative

This module holds an alternative view formatter for the "Add to cart" formatter that exists on the Drupal Commerce's Cart sub-module.
Basically it shows a form with all the product attributes set as a Cart attribute but in a much more performant way.
This performance is achieved by skipping iterations over all product variations and attributes.
So it's perfect for product with lots of variants (performs well on tens of thousands) and if the product has variants for all possible combinations of products.
