Construct JSON-like values by using JSON syntax

This macro can be used to create Value instances using a JSON syntax. Value objects are used mostly when creating custom errors from fields.

Here are some examples; the resulting JSON will look just like what you passed in. ```rust

[macro_use] extern crate juniper;

graphql_value!(1234); graphql_value!("test"); graphql_value!([ 1234, "test", true ]); graphql_value!({ "key": "value", "foo": 1234 }); ```
