Oxygen text added to each render.cpp file for the default projects. Text includes project explanation from Wiki, edited in places.

Empty project added as a default project.

Doxyfile updated. Each of the project locations added to INPUT configuration option. Consider just watching the whole project file so all new projects are automatically pulled through.
