Add code snippet

[aureliosaraiva]

This is a proposal to change the way we get the code snippet in the documentation.

What this solves?

• Resolving a snippet problem is not valid
• Solve the problem of updating the example and do not remember to update the snippet
• Possibility of catching snippet of controller, component, route

This project also use it.

https://github.com/ef4/ember-code-snippet

If they agree, I can replicate it for all the documentation.

I like this method and use it in other projects.
I particularly like that the code which is used to produced the view is then available to see.

If highlightjs is gone are these necessary?

Highlightjs is dependency https://github.com/ef4/ember-code-snippet/blob/master/package.json
