[BioPython] first,last sequence # in PDB file

[Douglas Kojetin]

Hi All-

I've tried (for awhile) to figure this out ... can anyone tell me how 
to extract the first and last sequence number in a PDB file?  If the 
PDB started at 1, I could figure it out easily from the sequence length 
(code from a recent post).  But, what about, for example, when the PDB 
starts with residue 5 and ends on residues 120. I /tried/ to dig 
through the documentation for a reference to sequence numbers ... it's 
probably just a problem with my eyes!

Thanks,
Doug
