Finish Website

I added the following to the website

1. Button for evaluation an expression
2. Reload ast and LaTeX only if there is no input for 500ms
3. Tutorial on the Home page to show all features
4. Info page for additional information
5. A footer with info about the build (commit, branch, time)
6. Improve colors especially for light mode

I also noticed that my project can’t be cloned on windows because windows doesn’t allow * in filenames. I updated the filenames but old commits still can’t be checked out easily.
