6a3e0e8: Customize SfFacet type with getFacetType config method.
Filter out facets data from searchProducts API method with filterFacets config method.
1eaf5372: Fixed attribute id normalization in normalizeAttributes. Previously it took attribute id (option_id in BigCommerce), not the id of the value. Fixed fetching variants in getProductDetails. Previously an empty array was returned. Fixed SfCart normalization - empty email now will be set to null, and line items will include a discounted price.
Created 4 API methods for getting currently logged in customer profile, login, logout & register on the store. Also, created normalizer for SfCustomer for BigCommerce.
