"""
Tips:
1. Do not rename the MyApp class and its five methods!
2. Return values of load_data, local_training, and global_aggregation methods will be communicated!
3. Return values of write_results will be discarded!
4. App supports five scenarios:
    * Native:
        - Centralized
        - Simulation of federated: No SMPC support
    * Containerized:
        - Centralized
        - Simulation of federated: No SMPC support
        - Federated
5. Containerized federated settings will be used in workflows for real world- collaboration
6. APP_NAME is case-sensitive and should contain the name of the app as a string and match the name of the config file
7. The config file should always named as `config.yml`
8. file structure:
    * Native
        - Centralized:
            data_dir to a directory containing all files for centralized training
        - Simulation:
9. transition loop between local_training and global_aggregation will continue until `last_round` attribute becomes True
