Troubleshooting for devs

• common error when editing model types (problem/solution/sysmodel):

  • no such column: ackrep_core_systemmodel.<...> or no such table: ...

  • fix: rebuild database

    • run ackrep --bootstrap-db

    • change working directory to ackrep_core and run python -c "from ackrep_core import core; core.load_repo_to_db('../ackrep_data')"
