Pair zero is a dummy pair interaction useful for requiring a
force cutoff distance in the absence of pair-interactions or
with hybrid/overlay if a larger force cutoff distance is required.
This can be used in conjunction with bond/create to create bonds
that are longer than the cutoff of a given force field, or to
calculate radial distribution functions for models without
pair interactions.
