I'm not sure if this is related to my previous ticket, #37 - I don't think it is, but if you find it is feel free to merge.
It seems that a cloudant addon is required for the vulcan app to run successfully. Nowhere in the documentation does it say those, nor do the error outputs of the server crash give any indication that cloudant is the issue.
It should at the very least be put in the README, but even better just automatically add the addon in the create function.
This will fail if your Heroku account is unverified.
