Remove if __name__ == "__main__" bits, replace some == None to is None checks Cleanup variety of static code checker issue Removed missing imports, restructured some logic to make a little cleaner, fixed a function in test_dockarea, unfortunately broke the test so now I tell pytest to expect the Exception.
