Goals

Have a GAEN-compatible library for testing and for apps that don't use the GMS. Targeted uses:
- Phones that do not have the Google Play services installed (e.g. Huawei).
- Phones running a free OS.
Developing a new complete library from scratch would be a significant amount of work (~2-3 months).
Optimization axes to pursue:
- Minimum amount of dependencies on other code.
- Smallest amount of changes in the Covid App.
