Coding rule

• Do not use TAB character. Use two spaces as an indent.
• Use default(none) for scoping of OpenMP-parallel region. E.g.

  #pragma omp parallel for default(none) private(idim) shared(wave,i_max,ie)
        for (idim = 1; idim <= i_max; idim++) wave[idim][ie] = 0.0;

• Variable declared with const must not be included in firstprivate of OpenMP scoping. Use shared.
• For MPI parallelization, use the following functions for I/O and abortation:
  • fgetsMPI() instead of fgets
  • fprintf(stdoutMPI,... instead of printf(...
  • fopenMPI() instead of fopen
  • exitMPI() instead of exit
• When you add new features into HPhi, please run make test, and check whether other features still work fine. Also, try make test MPIRUN="mpiexec -np 4" to check MPI feature.
