Bugs repaired

• name of the method in the schema was capitalized and in the java file not
• if method does not have parameters, then in the schema we should not put ()
• for schema mapping, method needs to be named as property in the schema.graphqls

type Person {
    firstName: String
    lastName: String
    personAddress: PersonAddress
}

    @SchemaMapping
    public PersonAddress personAddress(Person person) {
        return new PersonAddress("123 Main St");
    }
