Support loading of file through URI. Tried using sampler which does this embedding of code but focus did not work.

I tried the following code
together with pluing sampler which allows "Embed code samples taken directly from source files in your slides."
The repo is available at https://github.com/ldionne/reveal-sampler
Would be nice if one can supply a URI to the actuall file either by file:// or http
