Piazza Likes

Piazza Likes allows users to collaboratively like comment threads on the popular class forum Piazza.

Features:
- Like comments on Piazza similarly to Reddit
- Sort comments by post time (ascending, descending) and number of likes
- Likes are aggregated across users, allowing users to quickly hone in on the most useful comments in active posts

How it works:
- Users log in with Firebase Authentication
- User IDs are used to track likes by comment IDs
- Likes are stored in Firebase Realtime Database
- The Piazza DOM is enhanced with a 'sort' panel and 'like' options

Getting Started:
- Install the plugin
- Login
- Start liking!
