Per-event attendance

[nkansal96]

Motivation

This will help with allowing officers to get a list of people who attended an event. This is a feature that has been requested a lot and has been fulfilled by manually running sql queries, so this will automate that process.

To Do

• Create a reducer to hit the GET /app/api/v1/attendance/:uuid? endpoint and store the data in the state
• Show the number of attendees on each event
  Under the Event Analytics section, show the number of attendees on each event card
• Show a modal with a table that displays the attendees for each event
  When you click on the number of attendees on the event card, a modal with all the attendees should appear. The table should include name, major, year, points.
• Look into how to perform join operations using the Sequelize ORM
