* Derive `Show` instance for `ClientSSLKeyCertPair` * Add a couple client helper functions & add additional exports * Add `grpc-haskell-core` target; add `c2hs` dep * Fix examples broken by #68 * rm `build-tools` and `include-dirs` directives from toplevel `.cabal` * More `ClientConfig` fixes * Ensure examples are built
