/*
What is this supposed to do:
- It should call on the API to give it a certain number of comments, in the range x to y (this has to be implemented in the api)
- When it has called that, it should display those
- Dynamic links are there to navigate the user along the pages
- Comments are shown dynamically
- This panel can be shown or hidden (maybe)

AND VERY IMPORTANT!
- If a user submits a new comment, automatically put it on the page, no reloading
