Image name for collectiveaccess

[jbhanks]

When I try to run docker-compose as per the readme, I get an error suggesting that the repo name is incorrect:

Pulling backend (collective:latest)...
ERROR: pull access denied for collective, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

If I change the docker-compose.yml file to say pkuehne/collectiveaccess instead of collective, the compose proceeds:

root@devtest:/home/dev-admin/collectiveaccess# sed -i 's/collective/pkuehne\/collectiveaccess/g' docker-compose.yml 
root@devtest:/home/dev-admin/collectiveaccess# docker-compose -p collectiveaccess up -d
