This Expectation is used to compare the values in a column to a Prophet forecast, based on a timestamp in a second column.

expect_column_pair_values_to_match_prophet_date_model is a [ColumnPairMapExpectation](https://docs.greatexpectations.io/docs/guides/expectations/creating_custom_expectations/how_to_create_custom_column_pair_map_expectations)

Args:
    column_A (str):
        The name of the timestamp column
    column_B (str):
        The name of the column containing time series values
    model_json (str):
        A string containing a JSON-serialized Prophet model

Keyword Args:
    mostly (None or a float between 0 and 1):
        Successful if at least mostly fraction of values match the expectation.
        For more detail, see [mostly](https://docs.greatexpectations.io/docs/reference/expectations/standard_arguments/#mostly).

Other Parameters:
    result_format (str or None):
        Which output mode to use: BOOLEAN_ONLY, BASIC, COMPLETE, or SUMMARY.
        For more detail, see [result_format](https://docs.greatexpectations.io/docs/reference/expectations/result_format).
    include_config (boolean):
        If True, then include the expectation config as part of the result object.
    catch_exceptions (boolean or None):
        If True, then catch exceptions and include them as part of the result object.
        For more detail, see [catch_exceptions](https://docs.greatexpectations.io/docs/reference/expectations/standard_arguments/#catch_exceptions).
    meta (dict or None):
        A JSON-serializable dictionary (nesting allowed) that will be included in the output without
        modification. For more detail, see [meta](https://docs.greatexpectations.io/docs/reference/expectations/standard_arguments/#meta).

Returns:
    An [ExpectationSuiteValidationResult](https://docs.greatexpectations.io/docs/terms/validation_result)

    Exact fields vary depending on the values passed to result_format, include_config, catch_exceptions, and meta.
