With Tim Driscoll's support I have changed the implementation of many
important predefined sets within Jmol.

Most predefined sets related to protein & nucleic were affected. We
believe that these are much more useful definitions.

Please be on the lookout for bugs.

Oh yes ... this work had a beneficial side-effect in the area of
nucleotide graphic shapes. I encourage you to load up some DNA/RNA, in
.cif or .pdb format, and try:
  cpk off; wireframe off; cartoons

Detail
------

The definitions of the following were affected:

protein - now includes modified residues
backbone/mainchain - for protein now includes OXT & appropriate H
sidechain

nucleic,dna,rna,purine,pyrimidine,a,c,g,t,i,u,tu ...
... all have new robust definitions provided by Tim.

Tim,

Your document was extremely helpful for me. I added it to cvs so that we
don't lose it.

Over the weekend I rewrote all the Group support code. Previously I told
you that this code was a disaster ... the infrastructure it is now in much
better shape.

I think the class hierarchy underneath Group is now quite solid:
Group
  Monomer
    AlphaMonomer
      AminoMonomer
    NucleicMonomer

Chain
  Polymer
    AlphaPolymer
      AminoPolymer
    NucleicPolymer

In addition, the mechanism for detecting groups is now very good. I think
we will be in a good position to add carbohydrate and lipid support at
some point down the road.
