-------------------------------------------------------------------------
1. How to Compile
-------------------------------------------------------------------------
Make sure you have GNU Fortran (gfortran) or Intel Fortran (ifort) installed.
Run the following compilation command in your terminal:

  gfortran -O3 binary_diffusivity.f90 -o binary_diffusivity
