Landing Page v 1.0

## This will be the first iteration of the Landing page.
React must be used to build the landing page, use Class components whether or not there will be states

### Features
**The landing page must contain** *(You can use see [fiverr's site](https://www.fiverr.com/) if you need a guide)*
- A **search bar**: that takes user data and can sends it to a back-end server for processing. Dummy data should be used for now, but when the server endpoint is exposed, the URL should simply be added to the front-end to make it work. Preferably, an AJAX fetch request should be implemented.

- **Buttons**: The landing page should contain buttons for:
- Sign-in and Log-in, which would link to [Auth0](https://auth0.com/), which will be used as our authentication platform. For now, leave the link field empty.

More features will be added to this issue until we have a working version of our landing page. The landing page should not be too integrated as it would be a separate service when we eventually refactor to a microservices architecture
