Use configparser to define/use the components definition

[jypeter]

I have been making some changes to the components' lists defined in run_C-ESM-EP.py

It coud be nice to have the definitions stored in .ini or .conf files outside of run_C-ESM-EP.py. This way you don't have to alter the source of run_C-ESM-EP.py if all you need to do is define or re-order components

The config files could go to a Config directory, e.g. Config/components_def.conf and Config/components_user.conf (to separate the default and user conf). There are probably some other places where this could be used in C-ESM-EP, in order to reduce the changes a user has to make to .py files (e.g. define the email variable in a config file)

I think this can be done quite easily with configparser. Maybe I'll try to do it if I have time, and this issue can be used as a reminder. I have also covered configparser in pages 55-59 of my old Plus loin avec Python tutorial
