Sequence Quality Trimmer Element

This tool scans each input sequence from the end to find the first position where the quality is greater than or equal to the minimum quality threshold. It then trims the sequence to that position. If an entire sequence has quality less than the threshold or if the length of the output sequence is less than the minimum length threshold, the sequence is skipped.
