Added web server that serves up our website, organizes dir structure

This adds a flask webserver to serve up the website sef made.
I also organized the directory structure into a few separate categories that I'll add to the Readme:

- src: For now the C stuff is going to go here
- static: static files, should be organized into js, css, and images later on
- templates: html templates
- application.py: our main flask webserver implementation
