We need to handle the interactions for atoms who are involved in the same rigid body as well as some short range interactions (bonds, bends, torsions) differently from other interactions.

We'll still visit the pairwise routines, but with a flag that tells those routines to exclude the pair from direct long range interactions. Some indirect interactions (notably reaction field) must still be handled for these pairs.
