Fully functional card vault management control panel for braintree.

You need redis running. `$REDIS_URL` works as expected if needed.

    cp braintree.dhall.example braintree.dhall
    $EDITOR braintree.dhall # insert sandbox tokens from braintree
    bundle install --path=.gems
    BRAINTREE_CONFIG=./braintree.dhall bundle exec roda server
	 
Visit `http://localhost:8080/<jid>/credit_cards` to manage credit cards for some JID.
