[BioRuby] Problems with Bl2seq parser

[Trevor Wennblom]

Hi, I seem to be running into some problems with the new Bl2seq parser.

Ideally I'd like to be able to read the report the same way as blast 
reports:
  Bio::Blast::Bl2seq::Report.xmlparser(filename_bl2seq_output).each do |hit|
    a = hit.identity
  end

xmlparser is undefined however, so we can try this:
  Bio::Blast::Bl2seq::Report.new(filename_bl2seq_output).each do |hit|
    a = hit.identity
  end

This doesn't give an error, but it wont read the report either.  This 
can be double checked with:
Bio::Blast::Bl2seq::Report.new(filename_bl2seq_output).to_yaml

What I have to do is the following:
  Bio::FlatFile.open(Bio::Blast::Bl2seq::Report, filename_bl2seq_output) 
do |ff|
    ff.each do |rep|
      rep.iterations.each do |itr|
        itr.hits.each do |hit|
          a = hit.identity
        end
      end
    end
  end

That's an awful lot of work for what should be a one-liner.  Am I doing 
something wrong here?

Thanks,
Trevor
