        """Core of the parser classes
        
        Collects all methods prefixed with "value_" and builds a dict of 
        their return values. Parser classes will inherit from this class.
        All methods that begin with "value_" in a parser class will be given
        the same `data` argument and are expected to pull their corresponding
        value from the collection.

        These methods return a tuple - their raw value and formatted value.
        The raw value is a string or tuple of string and the formatted value
        be of type string, int, float, or tuple.
        
        If no data is found in a method, the raw value is expected to be None,
        and for the formatted value, strings will be "null", ints will be 0, 
        floats will be 0.0.

        Args:
            data (dict): Raw video data 
            rawMode (bool): Returns raw values instead of formatted values
            includeMissing (bool): If value is missing, return "empty" value

        Returns:
            dict<str, dict<str, var>>: Parsed data from class methods, may not have every value.
