objects to represent orders
customer id is empty when there is no customer ... comment added
method to create orders
if product already exists, remove id from queue nevertheless
refactored, getGcConsumerId has its own method now
implement helper methods to create shipping/billing address and order item arrays
access api data by ID directly instead of using a json filter array
refresh product list for each page, so no product is exported only once
move missing methods for customer creation to api
get correct label for store, product doesn't contain store id
export is finished, when _ALL_ lists are finished.
don't loop when not products are in the queue
make sure the product list is saved in the end
make sure we get correct values later for products - when products are loaded too early, the gc_product_ids are not up to date
