Martin,

We had a bug on this which in turn we decided to add shebangs.

Following bug:

Yes it might or might not be in a tool box of sorts, but if we decide to add it to a toolbox or command line tool set to spit out barcodes which I do myself the shebands work great.

Python shebangs shouldn't be in modules, I removed them to comply with
general python coding practice. If there is a reason to add them back I
will, but the modules are none functional when executed and in a
separate directory so shouldn't be executed anyway.

Thanks for reviewing.

Martin,
