[Biopython-dev] Align

[Cayte]

  The sig in Generic.Alignment function, add_sequence,
    def add_sequence(self, descriptor, sequence, start = None, end = None,
                     weight = 1.0):

does not allow the caller to pass in the name of the sequence.  I think the
descriptor should have a default of the empty string and the name should be
part of the signature.

  I need the Alignment class for the SAF parser, because the SAF format
represents alignments rather than isolated sequences.
