[atlas] Sagan: 'Response' object has no attribute 'edns0'

Hi all, I'm trying to do some basic DNS UDM result parsing using Sagan.

I'd like to have an easy way to extract the NSID. I followed the
instruction found here:

https://www.ripe.net/ripe/mail/archives/ripe-atlas/2014-May/001475.html

'from ripe.atlas.sagan import Result
 result = Result("your-JSON-result-blob-here")
 print(result.responses[0].edns0.options[0].nsid)'

That didn't work, as I get:

AttributeError: 'Result' object has no attribute 'responses'

So I figured I need to use a DnsResult, instead. I then have the
following Python code:

 from ripe.atlas.sagan import DnsResult
 import json

 url = "https://atlas.ripe.net/api/v1/measurement-latest/1873691/"
 results = json.load(urllib.urlopen(url))

 for probe in results:
  sagan_result = DnsResult(results[probe][0])
  print(sagan_result.responses[0].edns0.options[0].nsid)

This gives me:

    print(sagan_result.responses[0].edns0.options[0].nsid)
AttributeError: 'Response' object has no attribute 'edns0'

After some digging through the Sagan documentation, I found out that the
way to do this should be:

 print(sagan_result.responses[0].abuf.edns0.options[0].nsid)


This might be of help to others.
