At present the patchwork implementation is very simple, just consisting of a function which calls the REST API. We want to create a fake patchwork for use in tests. So start a new module to encapsulate communication with the patchwork server. Use asyncio since it is easier to handle lots of concurrent requests from different parts of the code.
