Move all Fortran files to .F90
Created by: fxcoudert
This pull request is a possible fix for https://github.com/Slookeur/Atomes/issues/2
It makes all Fortran files .F90
, including the ones that are incorrectly .f90
but have preprocessor directives. There is no downside to preprocessing all Fortran files, including the files that currently have no preprocessor directive. Therefore, I think it is the simplest fix.
