CAH implemented in hubot form. I take no credit for this implementation. I am merely moving this script from the old hubot world to the new NPM-packaged one.
Someone types hubot q card, and then everyone does hubot card me (or hubot card me 2, if it's a take-two).
Add the package hubot-humanity as a dependency in your Hubot package.json file. Then add hubot-humanity to the list in the external-scripts.json file.
