Batch Query implementation

[Mandeep Shrestha]

First of all thanks Sangria for making it easier to get into graphql, it has helped a lot.

I have been trying to implement Sangria Batch query, but running into some issues. I had asked similar questions, on the gitter chat, but this seems to be a better way to explain the problem, I am facing.

Took a fork of, Sangria Playground, and added batch query features as explained in the "Learn" page

https://github.com/mandeeeep/sangria-playground/tree/develop

Added a new controller with batch specific updates,
https://github.com/mandeeeep/sangria-playground/blob/develop/app/controllers/BatchApplication.scala

Schema objects with directives, 
https://github.com/mandeeeep/sangria-playground/blob/develop/app/models/SchemaDefinition.scala

val StarWarsBatchSchema = Schema(Query, directives = BuiltinDirectives :+ BatchExecutor.ExportDirective)

Now, on the appropriate route,

/graphql-batch

Request:

{

"operationNames":["SomeQuery","SomeQueryTwo"],

"query":"query SomeQuery{human_1000:human(id: \"1000\"){id,name}} query SomeQueryTwo{human_1001:human(id: \"1001\"){id,name}}"

}

Response:

{
    "data": {
        "human_1001": {
            "id": "1001",
            "name": "Darth Vader"
        }
    }
}

Is the query sent not batch query specific, or am I doing something wrong with the batch features implementation.
Any tips would help.

Thanks,
