Add sample data

[cuducos]

This might be useful to easily get started with a development environment — as suggested in #120.

Also useful when Rosie and the toolbox are temporally not available — isn't it @jtemporal?

Really? This is just sample data. Not the full dataset. I expect to use it just to easily build a development environment, not to replace the whole dataset download and creation (that should be delegated to Rosie).

@cuducos it is about development mode :) I will create a new Makefile target.

[jtemporal]

@cuducos and @gomex merged =)
