Consider rewriting agents inheriting from the (new) abstract base class Agent(Met4FoF) to MesaAgentMet4FoF and OSBrainAgentMet4FoF

[BjoernLudwigPTB]

The longer I work my way through the agents, the more I think it is worth considering to split up all classes that provide distinct behaviour depending on the string attribute backend. It seems to me a more OO approach would be inheriting from a generic(/abstrcact) base class and rewriting (currently) two agent classes for the two backends. Somewhat similar to what we did with the dashboard (due to the need for distributed capabilities of multiprocess.context.Process).
