Lists get added sequentially to keep them in order.
Trello is a little bit shaky when it comes to setting list positions, I think they assign position values based relative to lists already on the board, so adding lists asynchronously doesn't get them in the right order even when I specify position values.
Added vars.json to move out some constant values
Added cli_utils as a module to require inside a node repl. Just copypasta for now.
