Introduce helper to create an alias
npm SOAP doesn't declare the namespace it uses for array elements in the XML, so XML parsing fails. There is however a workaround for that on stackoverflow. As for all problems in life.
See: https://stackoverflow.com/questions/30740415/namespace-for-array-field-in-node-soap-client-node-js
FIXME: The helper doesn't update local user objects to include the new alias. That might be nice. Or not. Who knows?
