Setting up crude demo

Amber and Trapped included.

index.html added with snippets, code added that uses Trapped.

From now on, you can play with HTML, refining the look and feel by playing with snippets retaining their name and code will still work.
Or you can refine the code by adding more logic behind it (now no one modifies model, you can see how it changes only when doing it manually as seen in last commit message).
