saving rules v1 instead of v2 to /output

setup_cell_rules() is calling export_rules_csv_v1( rules_file );

I believe that means that it also prints the base value, correct? Which I find useful.

Hmm, fair point. Just don't try to import that v1 version of the rules in the current version (2.37.*) of the Studio. I guess we should allow for importing v1 rules, but presumably we would also want to check the base value there with what the Studio currently has.
