Create some kind of queue for processes

[Kraysent]

There are a lot of situations where one might want to do the following things:

• Run creation, then integration, then analysis.
• If created models already exists, skip it and go straight to integration
• If model is already integrated, skip it and go stright to analysis
• Run several creation -> integration -> analysis cycles in paralllel

It would be a good idea to create some centralized solution for this akin to Makefile.
