This contains several pieces:

server.js and lib/routes.js define the basic web server side of things. There

  are currently a few API endpoints, and navigating to / will deliver an HTML

  page (which is included in the frontend change).
lib/slack.js has code to query our Slack logs from Amazon DynamoDB, as well

  as get the user list from the Slack API.
lib/students.js has code to load the students.json file as well as merge in

  Slack avatars.
lib/reviewboard.js has code to query the Review Board API.

Exercised all of this via the frontend.
