Only Michiel has replied, so I assume there are no other strong views on 
the dev mailing list.

You have persuaded me to rename SequenceIterator and WriteSequences.

BioPython uses the term "parser" all over the place.  Doing a quick 
search of the code, I found ten files with "def read(" and  fifty eight 
with "def parse(" - so I would rather have "parse" than "read".

That would give us the core functions:

Bio.SeqIO.parse(handle, format)
Bio.SeqIO.write(sequences, handle, format)


Bio.SeqIO.read(handle, format)
Bio.SeqIO.write(sequences, handle, format)

I'll let you [Michiel] make the call.  Say the word and I'll update the 
code and the wiki today.

Are you happy with Bio.SeqIO.SequencesToDict(...) name?

I think we should keep Bio.SeqIO.SequencesToAlignment(...) for the time 
being, until we do some work on the Bio.Align class.  I don't think we 
should tackle this before the next release.  I'm happy to document this 
particular function as "experimental/beta" and liable to be removed or 
replaced in future.

After the renaming, I would say the Bio.SeqIO code is OK for release.

After BioPython 1.43 is out, I would like to mark the old code in 
Bio/SeqIO/FASTA.py and Bio/SeqIO/generic.py as depreciated.
