Port to Traceur

[esco]

https://github.com/google/traceur-compiler

Traceur is an ES6 --> Today's JavaScript compiler created by Google. It has the approved and some proposed (not final) features of ES6 harmony. It offers the same benefit as typescript in terms of modularity while being much closer (if not exactly) the same syntax that will be implemented for the next version of Javascript.

thanks for the suggestion.

Traceur includes very nice features, but it lacks one that is quite important for us, and that is static type checking. I hope that in time TypeScript will include most of the features that are available in traceur today.
