/* ERROR/WARNING messages:

E: Atom style hybrid cannot have hybrid as an argument

Self-explanatory.

E: Atom style hybrid cannot use same atom style twice

Self-explanatory.

E: Cannot mix molecular and molecule template atom styles

Self-explanatory.

E: Per-processor system is too big

The number of owned atoms plus ghost atoms on a single
processor must fit in 32-bit integer.

E: Invalid atom type in Atoms section of data file

Atom types must range from 1 to specified # of types.
