fix linting issues
after loading the mflow module, cd into your workflows checkout directory and run:
$ pylint --rcfile=mflow.rc --output-format=text $(find ./mflow/workflows/life-science/StructureBasedScreening/scripts/ -type f -name "*.py")
Resolve all issues.
There is one problem: Biopython is unknown to mflow. Either we make it a dependency of mflow or not. Thoughts?
Same goes for modeller, but that should be an exception for the import anyway.
