[maker-devel] CDS retrieve from augustus_masked

Augustus only predicts UTR for a handful of organisms.  I trim them off the
rejected models before outputting to the GFF3 as match/match_part features
(per my previous e-mail concerning the limitations of GFF3).

Thats a good point because 'transcripts' implies that it would have the
UTRs. Does augustus predict the UTRs?  I manually checked the translations
of the .transcript. file and I only found valid translations but that does
not mean that UTRs could not be present...
