I pushed a first version of my patch.

Known issues & remarks:

• Verbosity option is completely broken
• Scheduling in task_master method can be improved
• Code duplication (_perform_experiments_for_single_id and _perform_parallel_experiments_for_single_id.
• Some names can probably be improved.

I'm leaving this in new state for now.
