+      rpcserver package -> server package
+      JSONRPCClient to Client
+      JSONRPCRequestBatch to RequestBatch
+      JSONRPCCaller to Caller
+      StartHTTPServer to Serve
+      StartHTTPAndTLSServer to ServeTLS
+      NewURIClient to NewURI
+      NewJSONRPCClient to New
+      NewJSONRPCClientWithHTTPClient to NewWithHTTPClient
