Responsive Curved Sections Huddle Landing Page

This was really hard to refactor. The original HTML was unreadable, the responsiveness of the website on the original solution was thrash, there was no documentation about the project on my original README.md. I made the HTML way more readable, deleted classes that were not used, simplified the CSS where it seemed fit, added functional media queries, improved responsiveness a lot, and made an extensive documentation about the whole of the project (This documentation can be seen in the README.md of the github repo).
