anchor.diff:  - the header stores key information so there is no longer the requirement that the writers and reads be configured the same.
   - you don't need to know how big the message is.
   
  -=== Performance
  +=== What is the performance like?
   
   While Vanilla and Index Chronicle support sub-microsecond latencies. If you use Wire the typical latencies tend to be around one micro-second.  You can still use raw writing of bytes if you need maximum performance.
   
  
positive.code: appender.writeDocument(wire -> wire.write(() -> "FirstName").text("Steve")
                                     .write(() -> "Surname").text("Jobs"));
