Parameter	Description	Type	Default	Required
encoded_column	Encoded column field to be added into the output file.	int	-1	NO
output_name	Output file name with match results.	string	<current_timestamp>.csv	NO

3. Guidelines

Instantiate CsvFile structs for the data CSV file and for the CSV file with the encoded fields.

matcher.CsvFile{
    Delimiter: ';',
    FilePath: 'data.csv',
    MatchColumn: 3,
}

3.1. Instantiate Csv Matcher

Instantiate a Csv Matcher by running NewCsvMatcher method. Insert two CsvFile structs: one for Csv data file; and the other one for the encoded data Csv.

matcher.NewCsvMatcher(
    matcher.CsvFile{
        Delimiter: ';',
        FilePath: "data.csv",
        MatchColumn: 3,
        StartLine: 1,
    },
    matcher.CsvFile{
        Delimiter: ';',
        FilePath: "md5.csv",
        MatchColumn: 2,
        StartLine: 1,
    },
    "fileName.csv",
    0
)

3.2. Run Matcher

After instantiate a CsvMatcher struct, you may run Match() method as in the following excerpt.

matchStruct := matcher.NewCsvMatcher( [...] )

err := matchstruct.Match()

It will generate a new Csv file with the data file rows that matched with the encoded ones.
