[BioPython] Martel-based parsing of Unigene flat files

[Sean Davis]

I am relatively new to python and biopython (coming from perl side of 
things).  I would like to make a parser for Unigene flat file format.  
However, after digging through the LocusLink parsing code (as probably 
the most similar format, etc.), I'm still at a loss for how Martel-based 
parsing works.  I understand the big picture (converting an re-based 
parsing of a file into events), but it is the detail that I am missing.  
I know about pydoc, but the pydoc for much of Martel is not very helpful 
to me, at least not in my current state of knowledge.  Any suggestions 
on how to get started?

Thanks,
Sean
