On the left you can see the directory structure of the code for the Apollo Demo site. Clicking on one of the files on the left will display the source code or HTML file you click on in this body window.
HTML files, because indenting was lost when I imported them, are difficult to read on screen. Viewing most of this source code will be more clear in a real IDE or text editor because wordwraping in the browser makes certain lines unreadable. Also indenting was lost on the java files when I imported those aswell. I've added them back (manually), but sometimes things are less readable then they should be.
Certain blocks of text have a different background color; this is because they were used as examples.
