        Residues

A collection of residues from a PDB structure.

This class provides code to work with SCOP domain definitions. These
are concisely expressed as a one or more chain fragments. For example,
"(1bba A:10-20,B:)" indicates residue 10 through 20 (inclusive) of
chain A, and every residue of chain B in the pdb structure 1bba. The pdb
id and brackets are optional. In addition "-" indicates every residue of
a pbd structure with one unnamed chain.

Start and end residue ids consist of the residue sequence number and an
optional single letter insertion code. e.g. "12", "-1", "1a", "1000"


pdbid -- An optional PDB id, e.g. "1bba"
fragments -- A sequence of tuples (chainID, startResID, endResID)
