[Biopython-dev] Module reorganization for upcoming Bio.PDB enhancements

Hi guys,

I'm fine with your ideas regarding different wrappers for
Bio.PDB.Structure objects discussed last week, in particular:

- creating Bio.Struct.RNA or Bio.PDB.RNA with a Structure instance.
- having a structure.as_rna() helper method as suggested by Eric (but this
is no must).

I'd like to take what Joao does for proteins and add some basic equivalent
for RNA structures shortly after.

Best Regards,
