Acquire environment variables

You need to set the following environment variables:

• ESA_TOKEN: Esa API token. To generate, go "Settings > User Settings > Applications > Generate new token". Because this token is tied to a user, it is recommended to use the token generated by the user who is expected to access the Esa team for a long period of time.
• SLACK_TOKEN: User OAuth Token beginning with xoxp-. You can obtain it from the "OAuth & Permissions" section of the app's administration page.
