[GraphHopper] Tutorial for InstructionList usage

[Laura Barroso]

ohhhh, so that´s why I couldnt find the method...I think I already choose,
there's no turning back at this point of my app...I stick to 0.3 version
at list for now, plus is the stable one, right?

> Release 0.3 code is here
> <https://github.com/graphhopper/graphhopper/blob/0.3/core/src/main/java/com/graphhopper/util/InstructionList.java>.
>
> The code you're seeing is here
> <https://github.com/graphhopper/graphhopper/blob/master/core/src/main/java/com/graphhopper/util/InstructionList.java>
> and it's the current master in development.
>
> So you'll need to choose what version you'll use in order to follow its
> API.
> (and use also graphs built with that version)
