Create home page

[Nguyen-HanhNong]

Right now, the current website redirects you to the home page for the evaluations for COMP 2804: https://questions.carletoncomputerscience.ca

Ideally, we want to have a home page where the default URL will describe what the website is about and show the list of supported courses.

Here are the steps to solve the issue:

1. Create the home page under src/pages
2. Change the default URL to point to the new home page
