/*
Local is a Client implementation that directly executes the rpc
functions on a given node, without going through HTTP or GRPC.

This implementation is useful for:

* Running tests against a node in-process without the overhead
of going through an http server
* Communication between an ABCI app and Tendermint core when they
are compiled in process.

For real clients, you probably want to use client.HTTP.  For more
powerful control during testing, you probably want the "client/mock" package.
