/* ERROR/WARNING messages:
E: Atom_style line can only be used in 2d simulations
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 ID in Atoms section of data file
Atom IDs must be positive integers.
E: Invalid atom type in Atoms section of data file
Atom types must range from 1 to specified # of types.
E: Invalid density in Atoms section of data file
Density value cannot be <= 0.0.
E: Assigning line parameters to non-line atom
Self-explanatory.
E: Inconsistent line segment in data file
The end points of the line segment are not equal distances from the
center point which is the atom coordinate.
