Firebase

Synchronization with firebase

This feature is under development.

Plan for implementation

Connect local database with firebase cloud database
Use a separate script if you want to reset the firebase database to the current local database
If you use this script from serveral devices with the same firebase database,
- Data is only synchronized (downloaded) with firebase database at app startup or when explicitly requested
- Data is uploaded continuously (each time something in the database is modified locally)
