docs: The plugin executes the logic from one of the scripts depending on which
      splice region the variant overlaps:
          score5.pl : last 3 bases of exon    --> first 6 bases of intron
          score3.pl : last 20 bases of intron --> first 3 bases of exon
      The plugin reports the reference, alternate and difference (REF - ALT) maximumentropy scores.
