While generate the messages.proto , the message name of the return value for smart contract's constant function is incorrect.

For example ,there is a smart contract contain a constant getName function which has no input parameter and return a string.
After convert the .sol file to the .proto files ,it will generate an unexpected GetNameReq message instead of generating GetNameResp message in the messages.proto.

# function in smart contract
function getName() public constant returns (string) {
      return name;
}

# After execute sol2proto , the expected message name in messages.proto
message GetNameResp { 
    string arg = 1;
}

# After execute sol2proto , the actual message name in messages.proto currently
message GetNameReq {
    string arg = 1;
}

After tracing the code , it seems to be a typo at line 59 in the grpc/method.go
I suppose the method.RequestName() should be replaced with method.ResponseName().

The corresponding PR is here #17

When i follow the Usage instruction in the README.md ,
the two of separating *.proto files never come out.

After tracing the source code in main.go ,
i guess the --output flag is required.

So i try the following cmd then it generate two proto files successfully.
sol2proto --pkg pb --abi NameService.abi --output .

Is it correct to ALWAYS specify the --output flag
if i want to get two separating *.proto files?

Thanks.

I ran the example in grpc-contract but somehow there aren't any resp messages produced by sol2proto, the messages.proto file only includes GetNameReq, OnNameSetReq and SetNameReq, I used the abi you have in the example.
