Partial-equilibrium elasticity-based Behavioral-Responses results

The parameter_errors function assumes behavior is a dictionary

This function returns a string containing zero or more error messages
generated by calling the Tax-Calculator ParameterBase.param_dict_for_year
static method for num_years beginning with start_year.

def run_nth_year_behresp_model(year_n, start_year,
Implements TaxBrain "Partial Equilibrium Simulation" dynamic analysis
returning behavioral-response results as expected by TaxBrain.
The first five and the last function arguments are the same as for the
run_nth_year_taxcalc_model function in the Tax-Calculator repository.
The run_nth_year_behresp_model function assumes behavior is a dictionary
returned from the Tax-Calculator Calculator.read_json_parameters method
containing the assumed values of the behavioral-response elasticities.
