The choice of operators are the usual comparison operators.  The XOR
operation (exclusive or) is also included as "|^".  In this context,
XOR means that if either the attribute or value is 0.0 and the other
is non-zero, then the result is "true" and the threshold criterion is
met.  Otherwise it is not met.

The optional {error} keyword determines how the current run is halted.
If its value is {hard}, then LAMMPS will stop with an error message.
