31 
32  A given residue is either a Residue::LIGAND, Residue::AMINOACID,
33  or Residue::NUCLEICACID.
34 
35  The standard residue types are provided with names like
36  IMP::atom::GLY. New types can be added simply by creating an
37  instance of ResidueType("my_residue_name"). All user-added
38  residues are assumed to be ligands.
