Idea: Play object protocol #157

We could have a button to replay the protocol of a given object up to the error in the state machine, similar to how we do it in presentations.
Example: highlight new in code and highlight the method in the state machine with the state we get. We can do this up to the error point so that we show the developer what were the previous states and what we are at now.
However, this is only helpful if the errors are related to chains of states.
