Add templates for REUSE Software

[Ludee]

We make licensing easy for humans and machines alike. We solve a fundamental issue that Free Software licensing has at the very source: what license is a file licensed under, and who owns the copyright?

1. Choose and provide licenses
2. Add copyright and licensing information to each file
3. Confirm REUSE compliance

Examples

All code files (.py) should contain the header:

# SPDX-FileCopyrightText: 2016, 2018-2019 Jane Doe <jane@example.com>
# SPDX-FileCopyrightText: 2019 Example Company

# SPDX-License-Identifier: GPL-3.0-or-later

Markdown and text files:

UPDATE:

• "If the author is being paid by their employer to create a work, the employer is often the copyright holder." In order to fulfil both criteria (attribution of the copyright holder and scientific citation of the author), it is necessary to add both in the REUSE string.
• To add the year is not a MUST and doesn' offer any benefit, so leave out the year! Source: https://reuse.software/faq/#copyright-holder-author
