* Implement simulation.calculate `print_trace=True` argument. Options: `max_depth` and `show_default_values`
Examples:
python
simulation = scenario.new_simulation(trace=True)
simulation.calculate('irpp', 2014, print_trace=True)
simulation.calculate('irpp', 2014, print_trace=True, max_depth=-1)
simulation.calculate('irpp', 2014, print_trace=True, max_depth=-1, show_default_values=False)
