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.
This format is not correct. You need to use `<%= ENV["SECRET_DEV"] %>` like on line 22 of this file.
