The value *dist* is the current length of the bond.
The values *dx*, *dy*, and *dz* are the xyz components of the
*distance* between the pair of atoms. This value is always the
distance from the atom of lower to the one with the higher id.
The value *engpot* is the potential energy for the bond,
based on the current separation of the pair of atoms in the bond.
