gRPC web for dart over HTTP/1.1

Recently merged grpc-web support #109 uses an XhrTransport suitable for the browser. This project uses 'dart:io' for a regular HTTP transport for non-brower clients.

Although this is a hack/experiment to get gRPC working over HTTP/1 with https://github.com/improbable-eng/grpc-web; it has been in use for a while using this setup.

It provides an implementation of ClientChannel as suggested grpc/grpc-dart - issue 43

The message is unpacked using grpcwebstreamparser.js from github.com/grpc/grpc-dart

Only regular RPC calls have been implemented.

Sample Usage

final channel = useHttp2 == true
      ? new ClientChannel(...)
      : new WebClientChannel(...);

final client = BookServiceClient(channel);

client.getBook(new GetBookRequest()..isbn = new Int64(60929871));

TODO

• Streaming
• Create a HTTP Transport that fits well with the changes for grpc-web support #109 in grpc-dart.
