Hiding my API keys

Problem:

I don't want to expose API secret keys, but I still want to be able to commit my changes and push to github.

Solution:

• Install figaro gem
• set environment variables in config/application.yml

  my_api_key: 'weoi23urow234jerow67jerjerjwejr'

• make sure .gitignore ignores config/application.yml
• in the initializer code, (for my week3 app, I put this in config/initializer/twitter.rb) use ENV['my_api_key'] instead of hardcoding the api key
• after deploying to heroku, run this command to set heroku's env variables

figaro heroku:set -e production
