Added the initial Cart and CartItem models.
Added routing, controllers and views for the Cart and CartItem models. Improved validation for the CartItem model so CartItems can be removed by specifying a quantity of zero.
Added styling to the new cart elements. Formatted the css manifest file with SASS so the bootstrap elements can be used with SASS helpers.
Merge branch 'develop-cart' into develop
Added rvmrc config to the Pow development server configuration because Pow will no longer read the rvmrc files in future versions.
Added the money-mongoid gem. This gem provides integration for the RubyMoney money gem with Mongoid. This gem's Mongoid integration is superior to RubyMoney's own money-rails gem.
Configured the money gem to use the Euro as the default currency. Set the application locale to NL so number formatting is as expected.
Added a price field to the Product model, and updated the seed file to include product prices.
Added helper methods to Product for easy tax calculations. Added the rails_config gem to help with custom configuration elements (such as the tax percentage).
Added price methods to the Cart and CartItem models.
Updated the frontend views to display the product/cart prices.
Merge branch 'develop-product-prices' into develop
Webshop now has a cart and the products have prices.
