GitLab

the help is now only shown if specifically requested and if the script uses argparser or docopt for handling of additional parameters

added code snippet to show the help if no script parameter is provided or if the `--help` was requested

added script version check: copies of the used script are automatically stored in the results folder; re-running the script will check differences between the current and previous script and leaves the choice to the user of whether to overwrite existing data or not
