public class EmptyIndexOutput extends org.apache.lucene.store.IndexOutput
An output that is used to cause file references to exist, but doesn't actually allow writing.

This could just use an FDBIndexOutput and never actually write anything, but this helps fail earlier in cases where we never expect to write anything.
