def quality_parsed(mime_type, parsed_ranges):
return fitness_and_quality_parsed(mime_type, parsed_ranges)[<NUM_LIT:0>]<EOL>
Find the best match for a given mime-type against
    a list of media_ranges that have already been
    parsed by parse_media_range(). Returns the
    'q' quality parameter of the best match, 0 if no
    match was found. This function bahaves the same as quality()
    except that 'parsed_ranges' must be a list of
    parsed media ranges.
