[Biopython-dev] Kabat puzzles

[Cayte]

  Some web surfing convinced me that subscripted Kabat numbers as in the
following text, represent variable loops in an antibody.  So if I simply use
the  Sequence class and string the residues together like beads, that will
be misleading.
Should the loops be features or should I extend the class? Any more ideas?
I need to do more surfing and digging.
