CoffeeScript test

Trying to do something interesting. Check the original Javascript example by Alejandro F.Carrera here: http://es.dbpedia.org/Wiki.jsp?page=EsDBpedia%20Data%20Usage%20Examples

I think it would work better by compiling CoffeeScript into Javascript before, but I wanted to try this. The syntax is nice and CoffeeScript seems a good option if a lot has to be programmed in Javascript. For short things, the overhead may not pay off.
