cleanup of examples/social code?

[marcelvanwaaijen]

Looks like there is still some old code in the "social" example. If that is the case, is is possible to clean that? It might be confusing for people starting with graphql-go and trying to educate by example (like me) ;-)

@marcelvanwaaijen I haven't looked into it in details but my wild guess is that it was an existing example and when this feature was implemented we ended up adding graphql.UseFieldResolvers() which uses fields instead of methods. Then we started using the fields and stopped using the method. I would suggest opening a separate issue if this is the case as this one was related to adding the field resolvers feature, which is already done.
