Module ChainSeparator

Seperate PDB into continuous peptide chains for XPlor. Remove duplicate peptide chains. Required by pdb2xplor.py

This is vintage code. See Biskit.PDBCleaner for a more recent version (though yet lacking some functions).

To Do: Create an override for the chain comparison if one wants to keep identical chains (i.e homodimers)

Classes
