* echo client/server example: dead code removal, add command line params, improve output messages * Add nix-build result to .gitignore * Merge echo-client and echo-server directories to echo-hs/ directory; rename main modules accordingly * Use our protobuf compiler to generate bindings for the Echo service * Simplify echo.proto to just one endpoint; use highlevel client/server interfaces and codegen for echo example * Remove repetition counts and thread spawns from echo client, parameterize payload * Update default.nix
