Adding template of copyright info for code

[brad-getpassport]

Suggest adding template copyright information at the top of all the python code files, or possibly all the code that looks something like this:

"""
Filename:
Copyright (c) 2021 - Present
All rights reserved.
"""

That’s for using this repo with proprietary code?

We’ve been discussing the SPDX License Identifiers in issue #21. The repo here is under MIT License and you’re right: at the moment the files don’t have a license information header…

Okay, so maybe mention it as a "best practice" in the README as ensuring that the proprietary code has a license is valuable.

There is a difference between the copyright and license information. I recommend to add a pre-commit hook that checks such headers automatically and adds/fixes them if necessary, e.g., as the year changes.

The insert-license pre-commit hook might be useful?
