A printer?

Hi,

I didn’t see a printer in the repository anywhere, something like https://github.com/graphql/graphql-js/blob/master/src/language/printer.js.

So I wrote one: https://gist.github.com/dminkovsky/b5efd2df4a13c6c89a01c5c49fbdffc8#file-graphqlprinter-java

I haven’t fully tested this. But the AST I’ve needed to print has printed correctly. Thought maybe to contribute. Are there other plans for a printer?

Regarding the implementation/style, the way it is now, it could use some double dispatch with Node. But the big switch works. Also, I considered/attempted/aborted writing a reducing<String> visitor as in LB’s JS implementation, but the approach I took was just much simpler for me.

(Because I still had to go looking for this)

You can print by using the SchemaPrinter class.

SchemaPrinter schemaPrinter = new SchemaPrinter();
schemaPrinter.print(schema);

A direct jackson dependency is not an option, imho: We should add only dependencies we really need or want.
