 The {neigh} keyword determines how neighbor lists are built.  A value
-of {half} uses half-neighbor lists, the same as used by most pair
-styles in LAMMPS.  A value of {half/thread} uses a thread-safe variant
-of the half-neighbor list.  It should be used instead of {half} when

 {n2} uses an O(N^2) algorithm to build the neighbor list without
 binning, where N = # of atoms on a processor.  It is typically slower
 than the other methods, which use binning.
