Detects the domain REGEX from a set of candidate REGEX strings by computing the column_values.match_regex_format.unexpected_count metric for each candidate format and returning the format that has the lowest unexpected_count ratio.

Builds ParameterContainer object that holds ParameterNode objects with attribute name-value pairs and details.

Check the percentage of values matching the REGEX string, and return the best fit, or None if no string exceeds the configured threshold.
