/* ERROR/WARNING messages:

E: Create_bonds command before simulation box is defined

Self-explanatory.

E: Cannot use create_bonds unless atoms have IDs

This command requires a mapping from global atom IDs to local atoms,
but the atoms that have been defined have no IDs.

E: Cannot use create_bonds with non-molecular system

Self-explanatory.

E: Illegal ... command

Self-explanatory.  Check the input script syntax and compare to the
documentation for the command.  You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.

E: Cannot find create_bonds group ID

Self-explanatory.

E: Invalid bond type in create_bonds command

Self-explanatory.

E: Create_bonds requires a pair style be defined

Self-explanatory.

E: Create_bonds max distance > neighbor cutoff

Can only create bonds for atom pairs that will be in neighbor list.

W: Create_bonds max distance > minimum neighbor cutoff

This means atom pairs for some atom types may not be in the neighbor
list and thus no bond can be created between them.

E: Create_bonds command requires special_bonds 1-2 weights be 0.0

This is so that atom pairs that are already bonded to not appear in
the neighbor list.

E: Create_bonds command requires no kspace_style be defined

This is so that atom pairs that are already bonded to not appear
in the neighbor list.

E: New bond exceeded bonds per atom in create_bonds

See the read_data command for info on setting the "extra bond per
atom" header value to allow for additional bonds to be formed.
