QSO Graph: organization defaults

This repository holds what every QSO Graph repository shares:

• profile/README.md: the page at github.com/qso-graph.
• TEMPLATES.md: how every repository is built, released and presented, starting with What every public repository carries.
• .github/: the default issue forms, pull request template, SECURITY.md and CONTRIBUTING.md, which GitHub uses in any repository that has none of its own.
• scripts/: weekly checks across the organization: drift_check.py (a release published everywhere) and conformance.py (each public repository against What every public repository carries).

The documentation for users is at qso-graph.io.
