[generic_imitation] Dosed contagion

[leander-j]

Some agents only adapt after receiving several doses of incentive. An agent who once observes some behavior might not change theirs directly, but only after subsequently observing the same behavior, i.e. after accumulating a certain number of doses. Observing contrary behavior on the other hand would reduce the stack of doses again.

This essentially means introducing a memory and could also be implemented as remembering a fixed number of time steps and changing behavior if a personal threshold is exceeded.
