[Bioperl-l] Empty Seqs

[Hilmar Lapp]

I added the possibility to create empty sequences to
Bio::PrimarySeq (and thereby Bio::Seq), and support for reading
and writing empty sequences to fasta format in Bio::SeqIO. Entries
with an empty line following the description line as well as those
without the additional empty line are supported.

Note that if you initialize an explicitely empty sequence you MUST
provide the -moltype parameter. The reason is that a sequence must
have a moltype, and for an empty sequence it cannot be guessed
(which it is otherwise).
