This is a combination of many commits: --------------------------------------------------------------------------- final. add public/private for core classes. wip - big cleanup cosets. index<>, cosets<>, and group<> all defined transparent <void> overrides that operate directly on indices, not names inheritance hierarchy means one can drop or change generator names still missing path support. wip - named cosets fix lang test wip - named generators Move Group docstring away from specialization. Remove tc::Gen; use Group<void> remove tc::Rel add thousands separators for benchmark limits add generators list to tc::group remove pair_map
