My intention was to simplify the API, not have different ways to do the
same thing. Anyway, if you think it's useful to have both the methods and the
algorithms, I won't insist :)
Can you please add a section in the Gelly guide describing how/when to use
the translators? Thanks!

> Provide methods for translation of the type or value of graph labels, vertex
> values, and edge values.
> Sample use cases:
> * shifting graph labels in order to union generated graphs or graphs read
> from multiple sources
> * downsizing labels or values since algorithms prefer to generate wide types
> which may be expensive for further computation
> * changing label type for testing or benchmarking alternative code paths
