Bootstrap for styles/sendgrid

installed the twitter bootstrap gem to customize the application layout and forms. I also installed unicorn, foreman, and set up sendgrid for devise recoverable. Additionally I created two files called .env where I stored sensitive information such as sendgrid data as environment variables. In addition, Procfile was also created. Those files were added to gitignore so no sensitive data are exposed to the public. Moreover, I created a user account.
You don'y really need to install `foreman` for all environments because you'll only need to ensure this is available in the development environment. It's best to do something like this:

    gem 'foreman', group: :development
