Add shebang line

[bernt-matthias]

Could you add a shebang line to all python scripts, i.e. use #!/usr/bin/env python as first line. The advantage would be that the scripts can be executed directly.

Maybe you could also consider to add entry_points (https://setuptools.pypa.io/en/latest/userguide/entry_point.html) to your setup.py. Then they would be installed to the PATH when installed with pip.

Good to know.

The #!/usr/bin/env python is added to the scripts.

Currently, I am adjusting the scripts in PhaBOX (upgrading the program and adding new functions). If you have further suggestions, please let me know. Thanks a lot.

Best,
