Emit API definition in Swagger schema format

I'm currently working on it, and do you have any idea about api reponse status code?
grpc-gateway/runtime#HTTPStatusFromCode returns http status code from grpc error code, but I can't get error code from doc generator.

How about defining all?

+ Some protobuf file to declare swagger fields are required.

One additional note.
Google discovery doc seems like a fork of swagger without error codes.

@ceram1 Can you post your current WIP branch somewhere?

@philips Sorry for delay.

I uploaded on ceram1/grpc-gateway@3fcd9e2

It's just a backup commit, as I could not finish swagger support.

I used this command to test this, from $GOPATH/src/github.com/gengo/grpc-gateway/

go install ./protoc-gen-swagger/ && protoc -I. -I$GOPATH/src -I$GOPATH/src/github.com/gengo/grpc-gateway/third_party/googleapis  --swagger_out=. examples/a_bit_of_everything.proto

hey @ceram1, great job on swagger spec! How's it coming along?

@gosuri I can't do it more, but it will not be hard to build a google discovery document generator.

Gotcha! No worries :)
