With #364, we have all the Fortran interfaces to call the C routines / functions of Uno but it will be great to add the following:

• A complete Fortran example / test in interfaces/Fortran/test_uno.f90
• An compilation option to generate a Fortran module uno.mod
• A README.md in interfaces/Fortran
• Update the main README.md to specify that we have a Fortran interface for Uno

I can work on it after the INFORMS annual meeting (26 - 29 October, 2025).

It will be also great to do a script to automatically check if something is missing or need an update in the Fortran interface when we update the C interface (like we have for Julia).
