The ProcessPoolExecutor functionality has been removed from the web service, basically reducing it to running things in a blocking fashion. The problem with the ProcessPoolExecutor was that it spawned a lot of threads that were left running and wouldn't terminate properly. The most straightforward way to fix it is, for now, to remove the threading.
A Dockerfile has been added for running the web service in a container.
v.1.4.1
This is a bug fix release which makes sure that the undetermined percentage handler does not break when the yield is zero. Thanks to sarek928 for reporting it: https://github.com/Molmed/checkQC/issues/55
