// This tests the swift packagae
//
// It can be used with a real swift server which should be set up in
// the environment variables SWIFT_API_USER, SWIFT_API_KEY and
// SWIFT_AUTH_URL
// In case those variables are not defined, a fake Swift server
// is used instead - see Testing in README.md for more info
//
// The functions are designed to run in order and create things the
// next function tests.  This means that if it goes wrong it is likely
// errors will propagate.  You may need to tidy up the CONTAINER to
// get it to run cleanly.
