Simulator: json output representation of the event statistics?

[npinto]

Should we consider printing out a json representation of the event statistics? like e.g.:

Simulation stopped early as all validators have been unbonded; nobody left to propose a block!
Event statistics:

It might then be easier to parse them out if they need to be analyzed/optimized.
