    Thanks for the updates @greghogan. Could you please also add the new `GraphAlgorithm`s in the docs? And maybe explain when to use those instead of the Graph methods? Otherwise, it's good to merge imo.

> 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
