Right now the demo only shows source code for the cookbook examples

It's not obvious to users of the demo that the source code for the rest of the demos (e.g., mouse tracking) has to be looked-up on GitHub.

• option1: button that links to GitHub demo folder

• option2: distribute this code with the demo (like the cookbook)

• option3: overhaul the whole source distribution system, creating a script to convert all source code to a single file and read/write from that. This would make the distributed application much simpler.
