[Biopython] Gene ontology parsing

[Timothy Wu]

Hi

Is there a parser in BioPython for OBO v1.2?

If there isn't (at least I couldn't find it a while back), maybe I could
contribute a little. I've casually wrote an OntologyIO package with
"OboRecord", a scanner and consumer files. I may have not handles all the
stuff written on http://www.geneontology.org/GO.format.obo-1_2.shtml, but it
did suit my own purpose before. I don't know if anyone in the project will
be interested in it. I also do not know if my code will pass the quality
standard set forth by BioPython. I've also wrote a GoGraph structure that
allow me to look for stuff in the DAG, treating it much like a tree, looking
for "common ancestor" given two nodes, parent, child, etc. I've never
contributed code to any project before, so if these code can indeed be
contributed, perhaps some help from someone in the project would be needed,
thanks.
