    One can now choose between:
    `graph.translateEdgeValues(new LongValueToStringValue()))`
    `graph.run(new TranslateEdgeValues<>(new LongValueToStringValue()))`
    
    The latter is slightly longer but customizable with parallelism, etc.

> 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
