 and also provides reflection APIs for [gRPC](https://grpc.io/) as well.

-> This v2 branch is a work in progress. It is basically feature complete, but still needs more tests for

-> Note that the APIs are likely to change a little bit between now and a formal v2 release. Also note

-> should be rock-solid and least likely to see any further API changes.
