Templates for ICON Fortran codes
--------------------------------
- 'program.f90_template' is the template for a Fortran PROGRAM.

- 'module.f90_template' is the template for a Fortran MODULE.
   - All Fortran codes for ICON, except for the PROGRAM units must be
     embedded in Fortran modules.
   - Module files shall be named mo_<name>.f90.

- 'subroutine.f90_template' and 'function.f90_template' are the templates
   for Fortran SUBROUTINE and FUNCTION units.
   - Subroutines and functions must be embedded in modules.

- Please note that "!>" and "!<" are part of Doxygen's syntax,
  and _not_ part of the <placeholder convention> used in templates.
