Terminology structure decisions

Terminology/structure questions:

1. gen_support becomes?

• user_function_support
• or persistent_worker_support
• gen_support and sim_support which inherit from common code module.

2. gen_specs['in'] for persistent gens gen_specs['in'] gen_specs['init_in'] gen_specs['persis_in']

Do we have 'init_in' and 'persis_in' and drop 'in' (leaning towards) Or 'in' as regular input - but if 'init_in' is specified then use it.

3. Should utils become internal_utils.

4. Option to not check/send kills to cancelled sims

• Name? check_cancel? kill_cancelled_sims?
• Default is True.
• should this be combined with other speed options (like disabling safe_mode) in a compound option?
