[BioPython] Bio.Kabat and the Kabat Database

[Peter]

I've been looking though the modules in BioPython, and had a closer look
at Bio.Kabat written by Katharine Lindner in 2001 to parse files from
the Kabat database of proteins of immunological interest:

Quoting the website,

Does anyone use the Bio.Kabat code?  Could we (or should we) mark it as 
depreciated for the next release of BioPython?
