"""Run Experiment
This script allows to run one federated learning experiment; the experiment name, the method and the
number of clients/tasks should be precised along side with the hyper-parameters of the experiment.
The results of the experiment (i.e., training logs) are written to ./logs/ folder.
This file can also be imported as a module and contains the following function:
* run_experiment - runs one experiments given its arguments
