I wrote those when Bio.GFF was not part of Biopython and they are
really only there to support Bio.GFF.

It would probably be better to change the Bio.SeqUtils funtions to
work on sequence objects. I imagine the Bio.SeqUtils functions are
much faster since much of the work gets passed to the native function
