This method may be overridden by "parallel" output formats for writing nodal data.
Instead of getting a localized copy of the nodal solution vector, it is passed a NumericVector of type=PARALLEL which is in node-major order i.e. (u0,v0,w0, u1,v1,w1, u2,v2,w2, u3,v3,w3, ...) and contains n_nodes*n_vars total entries. Then, it is up to the individual I/O class to extract the required solution values from this vector and write them in parallel.
If not implemented, localizes the parallel vector into a std::vector and calls the other version of this function.
Reimplemented in libMesh::Nemesis_IO.

This method should be overridden by "parallel" output formats for writing nodal data.
Instead of getting a localized copy of the nodal solution vector, it directly uses EquationSystems current_local_solution vectors to look up nodal values.
If not implemented, reorders the solutions into a nodal-only NumericVector and calls the above version of this function.
