NoOpVisitor discards all JSON AST information.
This is the simplest possible visitor. It could be useful for checking JSON for correctness (via parsing) without worrying about saving the data.
It will always return Unit on any successful parse, no matter the content.

==Responsibility==
Generally, whoever creates the visitor should be responsible for closing it,
i.e. not intermediate transform(v: Visitor) methods themselves.

==Self Closing==
Given that common usage is most often single-valued (e.g. "{}"),
rather than multi-valued (e.g. "{} {} {}"), Visitors may self-close
(e.g. visitor.map{v => Try(v.close); v)} after a single value to
prevent resource leaks, but are encouraged to expose both forms
(i.e. single/multiple), if supportable.
==Multiple close() calls/Idempotency==
Visitors are encouraged to respond gracefully if close() is called multiple times.
If an underlying resource would throw if already closed, this may mean adding a
private var isClosed: Boolean field to prevent multiple calls.
