 We can write a resolver so that every message has an associated Student. We do this by creating a messgae type in which one of the fields is a STudent. The resolver currently goes to the message, looks at the students id, and gets the correspodning student. When you run teh example query, it is now able to map to a student object with all of it's fields.
