------------

This example shows how a collection of results can be read.

    from pathlib import Path

    def multiply(a: float = 1, b: float = 2):

        return a * b
    
    
    if __name__ == "__main__":
        # create model class
        model = make_model_class(multiply)
    
        # write data
        Path("data").mkdir(parents=True)
        for n, a in enumerate(range(5, 10)):
            result = model({"a": a}).get_result()
            result.to_file(f"data/test_{n}.json")
